Katherine Ardeleanu, MS, LGPC

Degrees: MS, Clinical Mental Health Counseling from Johns Hopkins University; BA from Northwestern University
Katherine's Focus: Katherine is interested in studying disparities in mental health and access to mental health services, as well as how to address these disparities and increase access to mental health care for under resourced populations. In addition to being a researcher and PhD student, Katherine is also a licensed mental health counselor and has seen firsthand in both research and clinical work how inequities in access to mental health services negatively impact people.
Katherine aims to address this issue in two ways. First is developing a better understanding of barriers to mental health care and how to address these barriers in order to improve accessibility of care. Second is researching mental health treatments for diverse populations and creating and implementing culturally informed treatments that are appropriate for minoritized groups who have historically been underrepresented in research.

Elochukwu Ezenwankwo, MSc (Med), MPH

Degrees:: MSc in Medicine from the University of Cape Town, SA MPH in Public Health from the University of Hertfordshire, UK
Elochukwu’s Focus: Elochukwu’s research focus has evolved quite tremendously in the past five years, spanning the broader areas of population health, implementation science, health services/systems, and global health research.
As a population health scientist and global health researcher, Elochukwu uses advanced research methodologies like realist methodologies, mixed-methods design, evidence synthesis, and participatory health research in developing and evaluating homegrown solutions to inform policy and practice adjustments that address health disparities (particularly in cancer care and service delivery) and improve survivorship outcomes in minority and underserved populations. Elochukwu is also developing capacity as a trial methodologist, supporting trial teams in designing and implementing inclusive and trustworthy clinical trials. Part of this entails supporting trialists and investigators in (1) effectively implementing Studies Within A Trial (or SWATs) to, for example, identify recruitment/retention challenges and plan bespoke strategies/interventions to address them and (2) investing efforts wisely in identifying and prioritizing patient-centered outcomes using, where they exist, tools like Core Outcome Sets [or COSs].
Elochukwu currently serves on the Editorial Board of BMC Health Services Research as a Board Member/Editor. He is also an External Reviewer for the NIHR Global Health Research Program and an International Collaborator on the IHME’s Global Burden of Disease, Injuries and Risk Factors (GBD) studies and the affiliate projects. Elochukwu has been selected for several competitive opportunities and awards, including the NIH/National Cancer Institute – CRDF Global Funded African Behavioral Research (ABeR) Catalyst Immersion scholarship; the Mandela Rhodes Scholarship, South Africa; and the African Organization for Research and Training in Cancer (AORTIC)— Global Health Equity Scholar award.
As a Doctoral Researcher, Elochukwu’s work at Drexel will examine, through a more realist lens, intersectionality and the overlapping factors that widen access and delivery gaps in lung cancer screening in typical urban resident minority communities.
