Steven M. Corsello
Assistant Professor of Medicine (Oncology)
Current Research and Scholarly InterestsOur laboratory operates at the intersection of functional genomics and chemical biology, with the goal of advancing novel molecular mechanisms of cancer inhibition to clinical use. We aim to 1) leverage phenotypic screening and functional genomics to determine novel anti-cancer mechanisms of small molecules, 2) develop new targeted therapy approaches against solid tumors, and 3) build a comprehensive community resource for drug repurposing discovery.

Helio Costa
Affiliate, Biomedical Informatics (BMI) graduate training program
BioHelio Costa, PhD, is a medical geneticist specializing in oncology, genomics, computational biology, data science, artificial intelligence, and product development. His work focuses on developing new cancer therapies and medical software to improve cancer patient care. He currently serves as Senior Medical Director and Head of Molecular Therapeutics & Drug Development at Natera and is an Adjunct Clinical Assistant Professor in the Department of Pathology at Stanford Medical School.
Dr. Costa’s research spans the entire drug development pipeline, from discovery to FDA-approved therapies. He leads efforts in developing innovative cancer treatments by integrating advanced genomics, computational biology, and AI-driven methodologies. His team focuses on the creation of targeted molecular therapeutics, using large-scale genetic data to identify novel treatment pathways and predict patient responses. In addition to drug discovery, Dr. Costa oversees the clinical trials necessary for validating these therapies, ensuring they meet rigorous standards for safety and efficacy. Furthermore, he manages the product development and commercialization process, guiding new treatments from initial research through to market-ready, FDA-approved cancer therapies.
In addition to his therapeutic work, Dr. Costa has led the development and implementation of genetic diagnostic tests and clinical algorithms used to support therapeutic decisions at Stanford Health Care. His contributions include the creation of DNA and RNA cancer diagnostic tests, as well as algorithms that analyze large-scale laboratory datasets and electronic medical records to predict patient outcomes. As a co-investigator with the NIH Clinical Genome Resource (ClinGen) Consortium, Dr. Costa oversaw developing FDA-recognized medical software used by healthcare providers, researchers, and biotech companies to assess the clinical relevance of genes and mutations.
He is the founding director of the Stanford Clinical Data Science Fellowship, where post-doctoral medical fellows engage in interdisciplinary clinical research and implement real-world health data solutions within Stanford Health Care. Dr. Costa is also an Attending Medical Geneticist for the Molecular Genetic Pathology Laboratory at Stanford Health Care, where he previously served as Assistant Lab Director.
Dr. Costa holds a BS in Genetics from the University of California, Davis, a PhD in Genetics from Stanford University School of Medicine, and completed his ABMGG Clinical Molecular Genetics and Genomics fellowship training at Stanford University School of Medicine. -
Alexandra Cours, MD
Clinical Assistant Professor, Medicine - Primary Care and Population Health
BioDr. Cours is a clinician educator in Geriatric Medicine at Stanford University, providing primary care for older adults and serving as a geriatric medicine consultant at Stanford Hospital. As Medical Director of the Acute Care for Elders (ACE) Unit, she leads specialized care for hospitalized older adults to optimize outcomes. She is also the Geriatric Section Director for Age-Friendly Health Systems, leading clinical and strategic efforts to advance age-friendly, evidence-based care across hospital settings and overseeing quality-improvement initiatives, including a delirium-reduction program. Dr. Cours leads a personal and professional development program for geriatrics fellows that prepares them for the transition to independent practice. In addition, she participates in the Foundations of Academic Clinical Excellence and Transformation (FACET) Faculty Development Fellowship and the Clinician Educator Scholars (CE Scholars) Program, which develop clinician expertise in ecosystem awareness, quality improvement, education, and clinical informatics through mentored initiatives that culminate in publishable work and career growth.

Heather Truher Cousins
Clinical Assistant Professor (Affiliated), Medicine - Primary Care and Population Health
BioDr. Cousins is a clinician educator based at the Palo Alto VA. She is board certified in Geriatric Medicine, Hospice and Palliative Medicine, and Internal Medicine. Dr. Cousins has an undergraduate degree from Stanford (Human Biology) and medical degree from the University of Chicago, and completed residency and fellowship at UCSF. She serves as medical director for the subacute nursing home (4C Short Stay CLC) at the Palo Alto VA, as well as for the VA Home Based Primary Care teams in Palo Alto and San Jose. Dr. Cousins serves as the primary faculty expert on geriatric palliative care for the Stanford Hospice and Palliative Medicine Fellowship Program. She is closely involved with teaching the Hospice and Palliative Medicine fellows in the long term care setting and teaches the Geriatric-Palliative care thread for the fellowship core curriculum. Dr. Cousins is the VA site director for the Home Care Medicine rotation for the Stanford Geriatric Medicine Fellowship Program. She also enjoys teaching history/physical and presentation skills to medical students in their second-year Practicum course. Her interests include supportive care for advanced cancer patients (especially head/neck cancer), nursing homes, home care medicine, transitions between care settings, elder abuse/neglect, and wound care.
