  1. Personal Statement

I am a vascular and cognitive neurologist with an extensive experience in clinical research and management of patients with neurocognitive disorders, with additional research training and experience in the fields of cognitive neuroscience and speech-language pathology prior to medical school. I am currently a Professor at the Department of Neurology, with joint appointments in Cognitive Science and Physical Medicine & Rehabilitation. I serve as a Deputy Director of the Neurology Department. My laboratory lab focuses on assessment and treatment of post-stroke aphasia and primary progressive aphasia, and identifying mechanisms of recovery of cognitive deficits after acute ischemic stroke. I have had continuous NIH funding for this research since the beginning of my K award, which started immediately after completion of my residency. I direct the mentorship and career development programs in the department, and served as the Residency Program Director for nearly a decade. Serving as the PI of the NINDS Research Education program (R25) awarded to Johns Hopkins has been exceptionally gratifying.  I have also served as the Senior Mentor for several previous R25 awardees.  One of my greatest passions is guiding the career development of young scientists in neurology, and I have especially found it rewarding to mentor clinician-scientists to become independent investigators. I have served as mentor for 5 K23 or K99 awardees and 1 AHA career development awardee, who are all independent scientists in academic positions; 1 is now a Professor; 3 are Associate Professors.  I am strongly committed to overseeing the research education of clinician-scientists and to improving diversity among clinician-scientists in Neurology.

  1. Contribution to Science
  1. Uncovering the cognitive mechanisms underlying naming, reading, and spelling – Most of my early publications focused on providing evidence for particular components of cognitive architectures of language tasks, based on detailed analysis of impaired patterns of performance on language by individuals with focal lesions (mostly chronic stroke).  By manipulating tasks and language stimuli in various experiments, and analyzing the influence of these manipulations on accuracy and the types of errors made, I was able to draw inferences about selective cognitive mechanisms that were impaired or spared in individual patients. I gained expertise in this type of analysis- the domain of cognitive neuropsychology- through collaborations with the Cognitive Science Department at Johns Hopkins University. We have had an impact on the field by characterizing many of the cognitive mechanisms and spatial representations underlying naming, reading, and spelling. I have had a lead role in many of these studies.

  1. Using cognitive models of language processes to guide rehabilitation of aphasia – I was a leading investigator in the field of aphasia in showing how a cognitive model of the language task to be treated, and detailed analysis of the cognitive processes that were impaired in an individual patient, might guide one’s rehabilitation or expectations from rehabilitation.  This research had an impact on the field of speech-language pathology (in which I was working at the time), as well my current research in rehabilitation of aphasia, combining neuromodulation with language rehabilitation. I directed this research, mentoring numerous speech-language pathologists and other trainees over the decades. This line of investigation eventually led to an edited book, The Handbook of Adult Language Disorders, which integrates a model of the cognitive processes underlying each language domain (e.g. reading) and a model of the neural mechanisms underlying the same domain, with the treatment of the same language domain. The second edition was published in 2015.

  1. Identifying the areas of dysfunctional brain tissue responsible for language deficits in acute stroke – Throughout medical school and residency I continued my research on aphasia. About the time I was completing residency, new magnetic resonance (MR) imaging of acute stroke was developed that could, for the first time, show areas of acute infarction and areas of hypoperfusion that were responsible for many of the language deficits in the first few hours of stroke.  Many chronic stroke patients I had studied had very large lesions and had recovered all but minor selective deficits in language. But it was impossible to determine what parts of the lesions were responsible for the deficits that failed to recover.  I started to study, on large scale, patients at the onset of stroke, before the opportunity for recovery or reorganization of structure-function relationships, identifying areas of ischemia and hypoperfusion (on MR diffusion and perfusion weighted imaging) associated with their deficits. Furthermore, I obtained additional evidence that particular areas were critical for a function by showing that restoring blood flow to a hypoperfused area could result in recovery of the associated language function.  I relied on this novel methodology for identifying areas critical to a number of cognitive processes underlying language (supported by a K23 and an R01 that has been renewed twice). I have consulted with other neurologists and cognitive scientists worldwide to assist or mentor them in using this approach to identifying areas of brain critical for specific functions, before the opportunity for recovery or reorganization.

C4. Identifying the underlying causes of Primary Progressive Aphasia and novel methods to improve communication or reduce the rate of decline. 

My long interest in aphasia led me to investigate the clinical syndrome of primary progressive aphasia, and what this clinical syndrome reveals about how language is organized in the brain.  My outpatient clinic currently focuses on management of primary progressive aphasia, and I follow one of the largest cohorts of this condition in the country.  We have carried out longitudinal functional and structural imaging studies and novel treatment studies in this unique population, and we are just beginning to carry out genetic studies in PPA and other neurodegenerative diseases.

C5.              Identifying mechanisms of recovery of language and cognitive deficits after stroke – My most recent work has relied on longitudinal functional and structural imaging and cognitive assessments after acute stroke and over the first year of recovery to identify the mechanisms of recovery of language and other cognitive processes.  We have been obtaining task-related and task-free (resting state) fMRI studies, perfusion, DTI, and other structural scans and detailed cognitive testing at 4 time points. While others have reported group patterns (e.g. a shift from mostly right hemisphere activation to mostly perilesional left hemisphere activation during language at the chronic stage), we have discovered marked differences in patterns of recovery across individuals and across language tasks within individuals. We have also demonstrated that different mechanisms of recovery (e.g. restoration of blood flow, recovery from diaschisis, reorganization of structure-function relationships) have distinct time courses. This work has led to some novel interventions to augment specific mechanisms at particular stages post-stroke, such as temporary blood pressure elevation to augment restoration of blood flow in acute stroke (pilot randomized trial), transcranial direct current stimulation with language therapy in the first few months after stroke to augment reorganization of structure-function relationships (ongoing cross-over trial).
