Rachael Ellison, PhD
Assistant Professor

Dr. Ellison is a clinical neuropsychologist who aims to intersect cognitive functioning with issues related to systemic inequities and social determinants of health.

Ellison is a clinical neuropsychologist and researcher, with expertise in applied neuropsychological research with a social and racial justice focus. Prior to her training in neuropsychology, her research and practice focused on issues related to social justice and social determinants of health (e.g., cultural competence, diversity, racial privilege, etc.). With Dr. Ellison’s current research, she aims to continue to intersect clinical neuropsychology with social and racial justice through her Socially Conscious Lab.

Ellison completed her postdoctoral fellowship in Clinical Neuropsychology through the two-year APA neuropsychology specialty accredited fellowship at Edward Hines Jr., VA Hospital (with specialized rotations in inpatient/outpatient neuropsychology, TBI, cognitive rehabilitation, and health promotion/disease prevention), and clinical psychology internship at the VA San Diego Healthcare System (with specialized rotations in neuropsychology, TBI, cognitive rehabilitation, and PTSD). She received her PhD in Clinical/Community Psychology from DePaul University. Prior to joining RFUMS, Dr. Ellison was a faculty member in the Clinical Psychology Doctoral Program at Illinois Institute of Technology.

Ellison is currently the Chair of the Women in Neuropsychology (WIN) Committee of the Society for Clinical Neuropsychology (SCN; American Psychological Association; APA Division 40), and engaged in private practice as a clinical neuropsychologist where she conducts comprehensive neuropsychological evaluations as well as cognitive rehabilitation. She was one of the inaugural editorial fellows for Neuropsychology’s Early Career Editorial Fellowship. Dr. Ellison was nominated and accepted to Northwestern University’s Council of 100 (membership by invitation only). She is an incoming council representative for APA Division 40.

Graduate Students

Christopher Gonzalez, MS
Christopher is a 5th year PhD candidate specializing in neuropsychology. His research interests include the cultural effects of subjective cognitive decline (SCD) and social determinants of health (SDOH), particularly in the preclinical stages of Alzheimer's disease. His other research interests are SARS-CoV-2, imaging markers, cardiovascular health, memory, and health disparities among English/Spanish speaking non-Hispanic Black and Latine/Hispanic populations. Christopher actively contributes to his field as the Student Representative-Elect Board of Directors for the Hispanic Neuropsychological Society (HNS) and as a Hispanic Serving Institution (HSI) Ambassador for New2Neuropsychology. Through these roles, he promotes collaboration and awareness of the challenges faced by underrepresented communities. He hopes to unravel the complexities of neuropsychology and advocate for marginalized communities with the ultimate goal of improving the lives of individuals affected by cognitive decline and related health disparities.
Humza Khan, MS
Humza Humza is a seventh-year Ph.D. student in the Illinois Institute of Technology’s clinical psychology doctoral program. He is currently a neuropsychology intern at the University of Washington at Seattle (UW) in the Rehabilitation Neuropsychology track. Before starting at IIT, he received his B.S. in Neuroscience at the University of Illinois at Chicago. Humza's current research interests include examining social determinants and health in the context of neuropsychology, specifically identifying differences between health information and executive functioning. His clinical interests include cross-cultural neuropsychology, demyelinating disorders, and dementia. Outside of research, Humza is interested in non-profit work, architecture, and racket sports.
Jared Cherry
Jared is a 2nd-year Clinical Psychology Ph.D. student specializing in Neuropsychology and a Clinical Psychology extern at the Captain James A Lovell Federal Health Care Center. He received his B.A. in History and B.F.A. in Music Performance from York University in Toronto. He has work experience as a teacher and course designer for multiple international educational institutions, and he has a variety of research experience with several Neurology, Neuropsychology, and Neuroscience laboratories throughout North America. His research interests lie at the intersection of neuroscience and psychology, focusing on the use of neuroimaging and neuropsychological assessment for the development and administration of cognitive and behavioral interventions such as psychoeducation, cognitive rehabilitation, cognitive training, and counseling.
Karen Basurto
Karen is 2nd year doctoral student in the clinical psychology PhD program at RFUMS, specializing in multicultural neuropsychology. Her academic focus is enhancing healthcare practices through comprehensive assessment and evaluation, particularly for Spanish-speaking Latin American populations. Her research has contributed to understanding the neuropsychological impacts of various socio-demographic factors and adverse experiences on cognitive and functional performance. Her interests span a wide range, from investigating health literacy in cognitive diagnostics to exploring neuropsychological challenges such as bilingualism/acculturation, epilepsy, and organ transplant care for Spanish-speaking patients. Recent work includes studying the impact of adverse childhood experiences on symptom and performance validity tests among patients with ADHD, exploring subfactors of adult cognitive disengagement syndrome, and assessing the limitations of performance validity using neuropsychological tests. Her contributions extend to clinical settings, such as her continued service as a bilingual neuropsychological psychometrist. Her work showcases a multidimensional approach to understanding cognitive functioning, health literacy, and neuropsychological assessment across diverse populations and clinical conditions. Beyond her academic and research pursuits, Karen is passionate about personal growth and community engagement. She enjoys learning new languages, volunteering, and teaching, which complement her academic work by broadening her cultural and individual perspectives. Karen also values time spent with family and friends, emphasizing a well-rounded approach to her professional and personal life.
Hannah VanLandingham, MS/MA
Hannah is a 5th-year clinical psychology Ph.D. candidate at RFUMS, and an advanced neuropsychology extern at The Neurology Center of Southern California. She previously trained at Northwestern Medicine, the University of Illinois Chicago, and the Edward Hines, Jr. VA hospital. She is primarily interested in integrating neuropsychology and rehabilitation in her areas of interest, namely cognitive health for underserved populations with complex medical conditions, brain injury and/or neurodegenerative pathology. Her current research centers on the impact of health inequities on cognitive functioning, cognitive rehabilitation, and examining the neurocognitive sequelae and profiles of various medical pathologies. Before attending RFUMS, she earned her M.S. in psychology at the Illinois Institute of Technology and completed her clinical master’s thesis on verbal and nonverbal processing speed discrepancy profiles for Veterans with co-occurring mTBI and PTSD. Moreover, she earned an M.A. in Psychology from San Diego State University and her B.S. in Psychology with a minor in English at Virginia Commonwealth University.
