Jennifer M. Curtin MD

Jennifer Curtin MD

Chief Medical Officer and Cofounder

Dr. Curtin is a physician and post-viral illness expert specializing in myalgic encephalomyelitis (ME/CFS) and its comorbidities. She is a member of the ME/CFS Clinician Coalition and co-authored the official clinical guidance for ME/CFS. Dr. Curtin has a personal understanding of the difficulties Long COVID patients experience as she is a mostly recovered ME/CFS patient herself. She understands the urgency that is necessary to understand Long COVID and bring her clinical expertise to the millions of patients currently seeking help.​


Ryan Kellogg PhD

CEO and Cofounder

Dr. Kellogg’s experience with complex illness led him to pioneer technology for molecular profiling using self-collected blood microsamples as a scientist at Stanford University. This allows for a better understanding of health fluctuations and the impacts of health interventions. When combined with wearable sensors and symptom tracking, this technology allows for real-time health monitoring and pattern discovery with unprecedented resolution.

Michael Snyder

Michael Snyder PhD

Cofounder and Chair of Scientific Advisory Board

Dr. Snyder is the head of Stanford’s Healthcare Innovation Lab, co-founder of multiple companies, and a pioneer in the use of wearable devices and app-collected data to understand, detect, and even predict changes in general health and disease. This technology allowed him to predict, detect, and correct his own post-viral diabetes. It is this wearable technology and health-tracking capabilities that play a key role in the treatment process here at RTHM.​

Stuart Malcolm MD

Stuart Malcolm MD

Clinic Director and Lead Physician

Dr. Malcolm is an internal medicine physician. He started treating Long COVID in March 2020 and has treated almost 100 patients with this illness (including patients with post vaccine issues).  Prior to RTHM, he was a primary care doctor with One Medical, where he saw how technology can advance medical care. He also served as a doctor at the Haight Ashbury Free Clinic, the oldest free clinic in the United States, and understands the importance of access to care. He believes that RTHM has the approach to cure Long COVID. He is excited to dedicate himself fully to this terrible illness. 

Melanie Minor

Melanie Minor

Clinical Program Manager

Melanie is an experienced Medical Assistant with a degree in Neuroscience from University College Dublin, Ireland. This knowledge base, paired with her own life-altering complex illness, gives her a strong understanding and unique perspective of how illnesses such as Long COVID can affect a person as a whole, mind and body. Since March 2020, she has chosen to work on the COVID front lines; starting in the ICU, then transitioning to school Isolation Rooms. Now, she is excited to team up with RTHM against Long COVID in search of a solution.

She has previously been at the Human Immune Monitoring Center (HIMC), Stanford University School of Medicine, for the past 15 years managing the immunoassay team, operations, and development of multiplex assays, as well as database and customer support. She led the research and testing of unique sample matrices and microsampling protocols.


Ian Simms

Operations Manager, RTHM Lab

Ian has drawn on his past as a cancer survivor for inspiration through his career as an analytical chemist. Bringing a wealth of chemistry knowledge to the team, he leads our mass spectrometry efforts and operations within the laboratory. His focus on targeted metabolomics will aid the ongoing effort to identify the chemical signatures of long covid and, ultimately, new targets for possible treatments. Ian enjoys racing sailboats and spending time on the water in his spare time.


Jille van der Togt

Data/AI Engineer

Jille is a graduate student in Artificial Intelligence at the University of Amsterdam. He has worked at numerous healthcare-related companies during his studies and with the biggest hospital in the Netherlands, using AI to identify novel markers in hematology data for certain diseases. He is currently helping RTHM with data-related tasks and finding better and more efficient ways to treat patients through machine learning.

Zach McMahon

Operations Manager, RTHM Lab

Zachary is a former educator that studied Mathematics at the University of California, Berkeley. Spending nearly ten years surrounded by numbers in and out of school, he has developed a logical, rational, and reasonable approach to every project he sets his mind to. While studying Mathematics in college, he developed a keen interest in nutrition, specifically, the effect food has on different individuals and societies. With a strong belief that nutrition can reduce the intensity of or even eliminate several physical and mental health issues, he has come to RTHM to help solve problems that are more complex than just a nutritional change.
