HIV Primary Care Physician & Infectious Diseases Researcher

I'm a physician who practices HIV primary care and studies how health systems succeed - or fail - at delivering good medicine.

In clinic, I care for people over time, focusing on prevention, chronic health, and the everyday decisions that quietly shape well-being. In research, I look closely at what happens when patients move through hospitals, clinics, pharmacies, and follow-up plans that are meant to work, but often do not.

Both roles ask the same question: What would care look like if it were designed for real lives?

What I Do

My work is split between patient-facing care and research, though the two are rarely separate in practice.

Clinical Work

Clinically, I provide longitudinal HIV primary care. This includes preventive care, management of chronic conditions, and attention to the foundations of health: sleep, nutrition, stress, medications, and continuity. I am interested in how these factors interact over time, and in how care plans hold up outside the exam room.

Research Work

Alongside this, I conduct implementation-focused research in Infectious Diseases. I study how evidence-based treatments are delivered in practice, where systems break down, and which interventions improve outcomes without creating unnecessary burden.

The clinic informs the research. The research shapes how I practice.

About

I trained in Infectious Diseases, but I practice as a primary care clinician for people living with HIV.

That combination matters. HIV care is inherently longitudinal and personal. It involves medical decision-making, but also trust, context, and sustained engagement. I am interested in how people live with chronic illness, how they make decisions, and how medical advice fits - or fails to fit - into the rest of life.

My approach to medicine is evidence-based and individualized. I care deeply about rigor, but I am attentive to uncertainty and tradeoffs. I am also interested in why good care so often depends on extra effort, and how systems might be designed to work more reliably for both patients and clinicians.

Care Philosophy

I practice HIV primary care with the belief that health is shaped as much by sleep, nutrition, stress, and trust as it is by lab values and prescriptions. My goal is to understand each patient as an individual - how they live, what matters to them, and what feels possible right now - and to build care plans that fit that reality.

I value evidence deeply, but I am equally interested in how evidence is experienced. A treatment only works if someone can access it, tolerate it, and return for follow-up. I try to be clear, collaborative, and honest about uncertainty, tradeoffs, and what we are aiming for together.

I also believe medicine should feel human. Kindness, curiosity, and a sense of proportion matter. Humor helps. So does listening carefully, changing course when needed, and recognizing that health is rarely a straight line.

Over time, my aim is simple: to be a steady, thoughtful presence, and to practice care that is both scientifically grounded and personally meaningful.

Training & Background

My training reflects a blend of clinical medicine and systems thinking:

  • MD - Johns Hopkins University School of Medicine
  • MS, Management Science & Engineering - Stanford University
  • Internal Medicine Residency (Primary Care Track) - Massachusetts General Hospital
  • Infectious Diseases Fellowship - NewYork-Presbyterian / Weill Cornell

For Patients

I provide HIV primary care focused on prevention, long-term health, and continuity. My clinical work includes HIV treatment and monitoring, sexual health and routine screening, and management of common and complex chronic conditions.

I aim to explain decisions clearly and to tailor care to what is workable over time, not just what appears ideal in theory.

For Collaborators

My research focuses on implementation, quality improvement, and outcomes in Infectious Diseases, particularly in populations at risk for fragmented care.

  • Inpatient-to-outpatient transitions
  • Hepatitis C treatment models
  • Drug-use-associated infections
  • Population-level analyses using Medicaid and health systems data

I am most interested in projects that begin with a concrete problem and lead to insight that can be used.

If you are building practical interventions in real clinical settings, I am especially interested in collaborating.

Selected Work

C's the Day: Inpatient-to-Outpatient Hepatitis C Treatment

C's the Day is a quality-improvement initiative designed to address a familiar gap: hepatitis C is curable, yet many hospitalized patients never begin treatment.

The program identifies untreated HCV during hospitalization, provides counseling, initiates direct-acting antiviral therapy when feasible, prioritizes medication-in-hand or arranged delivery at discharge, and supports low-barrier outpatient follow-up.

During the intervention period, 67 treatment-eligible inpatients were identified; 79% were assessed by the treatment team, and 19% initiated therapy, compared with 5% in the year prior.

The primary challenge has been post-discharge loss to follow-up, which has informed ongoing refinements to the model.

The project is less about achieving perfect metrics than about understanding which components of inpatient treatment are feasible and sustainable in real clinical settings.

Scholarship

My scholarly work focuses on translating evolving evidence into everyday clinical practice, particularly in HIV preventive care and vaccination strategy.

Outside the Clinic

Outside of work, I practice aerial silks, swim, and play piano. These pursuits keep me grounded and remind me that skill develops through repetition, attention, and patience - and that balance is less a fixed state than an ongoing practice.
