Anna Krason Joins MRRI to Work on Collaborative Research

Scientists and staff at Moss Rehabilitation Research Institute (MRRI) are pleased to welcome Anna Krason, MSc, to the Institute this month. Ms. Krason is a PhD Candidate in the Department of Experimental Psychology at University College London (UCL). Her dissertation supervisors are MRRI Scientist in Residence and UCL Professor Gabriella Vigliocco, PhD, MRRI Associate Director Laurel Buxbaum, PsyD, and UCL Professor Rosemary Varley, PhD. The focus of her dissertation research has been on multimodal communication and the impact of visual cues on speech comprehension in neurotypical individuals and people with chronic aphasia. These visual cues include the gestures and mouth movements that are integral to face-to-face communication. During her PhD, Ms. Krason was awarded UCL Bogue Fellowship and MRRI Peer Review Committee grant to visit MRRI and investigate the benefit of visual speech information to aphasic comprehension

Ms. Krason received her undergraduate and postgraduate training in French Philology focusing on Linguistics and Translation from the University of Wroclaw in Poland. Afterwards, she continued her studies there, obtaining Speech and Language Therapy qualifications. Next, Ms. Krason earned her MSc degree in Psychology and Language Science from UCL, specializing in Neuroscience and Communication. Drs. Vigliocco and Buxbaum served as her MSc supervisors on a project examining the integration of co-speech gestures in people with aphasia and limb apraxia. Prior to enrolling in her PhD program at UCL, Anna worked as a research assistant on a project investigating a computer-based speech comprehension therapy for individuals with aphasia. This therapy incorporated elements of gamification to increase user engagement.

At MRRI, Ms. Krason will be working on a joint NIH project led by Institute Scientist and Director of the Language and Learning Laboratory, Erica Middleton, PhD, and the Director of Neuroscience of Language Lab at George Washington University, Malathi Thothathiri, PhD. In this project, Ms. Krason will use EEG and eye-tracking methods to investigate the impact of cognitive control deficits on sentence comprehension in individuals with aphasia.

Ms. Krason will also continue her collaboration with the Language and Cognition lab at UCL, as well as with Drs. Buxbaum and Vigliocco on their project examining multimodal communication in aphasia.

With a background in speech and language therapy, Ms. Krason is particularly interested in the interplay between the brain and language. Her long-term research goal is to advance our understanding of cognitive and neural mechanisms underlying language and its impairments.


Transforming the Medical Record For Clinical-Research Integration at its Best

Computer monitor with the words "medical record"

Healthcare is increasingly turning to big data as a way to build health profiles and predictive models to inform diagnosis and treatment. In the future, it is likely that the types of algorithms that currently predict what movie a person would like to watch or what takeout they would like to order, could be used to select treatments that are personalized to your individual condition and needs.

Critical to achieving this future, however, is the ability to merge scientific information with clinical information derived from well-documented electronic medical records (EMRs). EMRs are replacing traditional paper-based medical records for good reason. These EMR systems can facilitate workflow and improve the quality of patient care and safety. Moreover, the data stored in the EMR may be used to conduct quality improvement initiatives, and it can be analyzed to gain scientific insights to guide models of care. In order to unlock the tremendous promise of these tools, it is important that the EMR is designed in a way that relevant clinical information can be extracted and properly classified.

Extracting data from EMRs for research purposes presents multiple serious challenges, as there is a lack of standardization with regards to the terminology used for diagnosis, clinical findings, and specification of treatments. This latter issue—treatment specification—is of particular concern in the area of rehabilitation. Researchers, including those here at Moss, have noted the lack of detail in descriptions of non-pharmacological behavioral treatments, such as those used in rehabilitative care. “Most rehabilitation treatments are defined in the chart by the discipline of the person providing them, the problem they are addressing, and the time spent on it. Very little is documented about the treatment’s “ingredients” — specific actions taken by the clinician to bring about the desired functional improvements. It’s analogous to an internist documenting that they spent 15 minutes providing large white pills to improve breathing,” notes John Whyte, MD, PhD, who has led and contributed to multiple federally-funded efforts to develop a rehabilitation treatment specification system.

Understanding what treatment factors and processes lead to better outcomes, and for which patient subgroups, would allow the development of more effective rehabilitation strategies. The information required to gain this understanding is very complex and requires capturing detailed information on injury type and severity; the types, timing, and amounts of interventions received; and how these factors affect outcomes across diverse types of patients.

To address this gap, Moss is participating in an effort funded through the National Institutes of Health, National Institute of Neurological Disorders and Stroke that will not only transform our local electronic documentation system, but also harmonize our EMR with 15 other leading rehabilitation hospitals across the country, to enable the largest study to date of the rehabilitation strategies and outcomes for persons living with Traumatic Brain Injury (TBI).

The study, called Comparing Treatment Approaches to Promote Inpatient Rehabilitation Effectiveness for Traumatic Brain Injury (CARE4TBI), is led by Drs. Jennifer Bogner, PhD (contact PI, OSU), Cynthia Beaulieu, PhD (MPI, OSU), and Erinn Hade, PhD (MPI, NYU). This pragmatic observational study will recruit nearly 1,600 participants through 15 TBI Model Systems sites, located across the United States in various health systems and communities. Using the standardized data captured during inpatient stays, the impact of naturally occurring differences in approach to rehabilitation therapy will be evaluated relative to their effectiveness in improving the person’s ability to care for themselves and to function at home, at work/school, and in the community through one-year post-injury.

Amanda Rabinowitz, PhD, is the Site Principal Investigator for the CARE4TBI study at Moss; Mary Ferraro, PhD, OTR/L and Andrew Packel, PT, NCS, are contributing to the multicenter, multidisciplinary team responsible for identifying and designing new data forms and response sets to be added to the standardized EMR; and Dr. Whyte is a Moss member of the study’s Steering and Executive Committees. The aim is to capture data chronicling treatment and recovery during the natural course of a patient’s hospitalization. Dr. Ferraro and Mr. Packel have been working with Moss administrators, clinical frontline staff, and information systems specialists to design EMR changes to capture this important clinical information accurately and efficiently, while ensuring that the changes integrate well into Moss’s current EMR to enhance daily documentation of care.

“It’s of great importance to the whole study team that the EMR changes not only support the research, but also fit within the clinical work-flow. This is why we have included the input of frontline clinicians and clinical leaders in our redesign efforts,” Dr. Rabinowitz states. The study team is hopeful that improvements to the EMR may create efficiencies in documentation and could confer benefits for the delivery of care. As Dr. Ferraro notes, “This process has raised important discussions about how therapists describe interventions and document patient status. With these modifications, there will be a better distinction between clinical assessments and therapeutic treatments, which is an essential step to the examination of care delivery.” And this is only the beginning. Dr. Whyte adds, “This project has led us to develop close working relationships among researchers, clinical leaders, and EMR designers and programmers. We hope this collaboration will lead to additional future projects that exploit the scientific value of a well-designed EMR.”

“We are very enthusiastic about Moss’s involvement in this project, and what it could mean for the future,” noted Dr. Rabinowitz. “We believe that the EMR changes that come from this clinical-research integration will pave the way for continued collaborations — both locally and with other TBI Models System sites — that have the potential to directly inform care.”


Catching Up with Former MRRI Postdoc Charlene Lee, PhD

Question List

  • Can you tell us more about your current position and what you are doing now?

I am an associate professor at National Taiwan University (NTU). My main appointment is with the Graduate Institute of Linguistics, and I also have joint appointments with the Department of Psychology and Graduate Institute of Brain and Mind Sciences, and I am a member of the NTU Neurobiology and Cognitive Neuroscience Center. My work mainly involves teaching, advising graduate students, and doing research. Other than that, I also help review papers for journals and recently took the associative editor position for Psychophysiology.

 

  • What are your research interests?

My research interests lie primarily in the area of language processing. Recent work in our lab focuses on the collaborative nature of the two hemispheres of the brain during language processing. For example, what is the role of the right hemisphere in acquiring syntactic regularities and what support can the right hemisphere provide when the dominant system in the left hemisphere deteriorates with age? We are also interested in understanding the predictive processing in the brain. For example, what kind of linguistic information do we anticipate prior to the actual perception of the inputs? What modulates our abilities to do so? What do predictions formed during language comprehension have in common with predictions formed during perception, actions, or other cognitive tasks?

 

  • Can you describe the impacts or potential impacts of your research?

Language is an amazing manifestation of human intelligence. Understanding how a complex system like language is deciphered in the brain brings us closer to the core of the human mind and provides potential help for rehabilitation or intervention. For example, our recent work showed that, although the right hemisphere is usually given little attention in the literature when it comes to syntactic processing, our data suggest that it has some morphosyntactic capacity (processing for both morphological change and syntactic agreement) that is similar to what the left hemisphere has. In addition, the right hemisphere is engaged to a greater degree during syntactic processing in healthy older adults. We also discovered that the right hemisphere can provide important contribution in the initial learning stage of syntactic regularities in healthy young adults.

 

  • What first attracted you to science?

I was interested in biology and mathematics as a kid. Growing up I become fascinated by how humans are capable of processing complex symbolic systems like language seemingly effortlessly. Language studies were categorized as humanities in the education system I was in. It was not until my senior year that I realized that what I was interested in could be studied in more scientific ways in linguistics and psychology.

 

  • Why did you choose to work as a postdoctoral fellow at MRRI?

I have always been interested in how language interconnects with other sensory-motor systems. At that time, Dr. Buxbaum had a research line that focused on embodied cognition and how different types of actions may differentially constitute meaning representations. I was very drawn to this hypothesis and thought that it was a great opportunity to learn how to systematically examine research questions like this. I was fortunate to have the opportunity to work as a postdoctoral fellow with Dr. Buxbaum at MRRI to learn more on this topic.

 

  • What was it like working in the Cognition and Action Laboratory at MRRI?

When I was in the lab, there were also other post-docs and full-time research assistants. Everyone was very friendly and professional. It was a very collegial lab. I still remember the help Dr. Solene Kalenine gave me when I first got to the lab, and those afternoons when people grabbed a cup of coffee and drew new ideas on the whiteboard!

Dr. Buxbaum is a very energetic leader, but she also kept things at a very reasonable pace. She gave us room to sharpen our skills and catch up on the literature that we may not be as familiar with as we wanted to be, and provided the help and resources that we needed. At a project meeting, her suggestions were always insightful and nudged the project in the right direction. J She is also very fun to be with. Her passions for science and music are very inspiring to me.

 

  • Is there something you learned at MRRI that has helped you in your current endeavors?

The research training I got from MRRI was very solid and had a great influence on me. Other than that, working at MRRI gave me many opportunities to work with people from various disciplines and to observe how people from different disciplines communicate and collaborate. These kinds of multidisciplinary experiences are very helpful in my current position.

 

  • What is one of your favorite memories from your time working at MRRI?

When I think about my time working at MRRI, the first image that pops into my mind is the regular lab meetings we had in the common area. Dr. Buxbaum’s lab had a weekly lab meeting with collaborating labs, including Dr. Dan Mirman’s and Dr. Steven Jax’s labs. Those meetings were always light-hearted and full of friendly comments and discussions. We were very productive, but things were done in a very collegial environment. Maybe that’s why I always remember it as a cozy afternoon scene with autumn sunlight.

I also like that our offices were among the areas where patients regularly came in for therapy sessions or social group activities. This and our clinical seminars that Dr. Kalenine mentioned in her recent interview really helped to flesh out my research experience as they helped me to see how different endeavors can all work together toward a common goal.

 

  • Can you tell us more about your long-term career plans or goals?

In my current position, I spend a lot of time working with ‘young students’ (master’s students or undergraduate students). I hope, with time, our young students will become mature and independent scientists. I very much look forward to working with them as peers and colleagues. Then it can be my turn to take a break to refuel my research energy! Eventually, I hope we can build a language science team at National Taiwan University and attract more talented local and international researchers to join us.

 

  • What are some of your personal interests or hobbies?

I like watching movies and reading novels. I also like to bring my kids outside to enjoy nature. Taiwan is a mountainous island. There are many easy and moderate hiking trails available, and it is also quite convenient to go to a beach.


MRRI Welcomes New Postdoc Dr. Yingxue Tian

Yingxue Tian

Moss Rehabilitation Research Institute (MRRI) is delighted to welcome a new postdoctoral fellow, Yingxue Tian, PhD, to their team of scientists. During the next three years, Dr. Tian will be working under the joint mentorship of Erica Middleton, PhD, in the Language and Learning Lab and Marja-Liisa Mailend, PhD, in the Speech and Language Recovery Lab.

Dr. Tian’s research investigates the cognitive and neural architecture of working memory, specifically the mechanisms dedicated to processing the serial order of verbal and visuospatial information units. To address this topic, she has relied on a wide variety of techniques, including the individual differences approach, the neuropsychological approach, and the network neuroscience approach.

Dr. Tian completed her undergraduate training in Statistics at Beijing Institute of Technology, and she earned her PhD in Cognitive Neuroscience from Rice University. In her dissertation, Dr. Tian investigated the intersection between working memory and spatial processing, identifying the behavioral and network-level neural underpinnings of the reorganization of working memory units in space. She has also investigated the generalization of inhibitory control from executive function to language processing after neuromodulatory (tDCS) training. Dr. Tian has received recognition for her early career research, including the Kenneth R. Laughery Award for Best Master’s Thesis in Psychology, the Pre-Dissertation Research Grant, and the Dissertation Research Improvement Grant from the School of Social Sciences at Rice University.

At MRRI, Dr. Tian will investigate the connection between language, working memory, and long-term memory. Specifically, she will study the relationship between the cognitive-linguistic profiles of people with aphasia and different types of speech errors. She will also investigate the individual differences in response to treatment from different training approaches for word retrieval in aphasia.

Dr. Tian’s long-term research goals are to advance our knowledge of the interplay between language processing and memory and to employ this knowledge for designing effective treatments that can facilitate recovery of disrupted cognitive functions after stroke.

Welcome, Dr. Tian!
