The Medical Toxicology Fellowship is an immersive, two-year fellowship that provides a diverse training experience, covering all aspects of medical toxicology.  Our mission is to provide the mentorship, resources, education and environment to allow for our fellows to become leaders to advance the field of medical toxicology.  Fellows will develop expertise in the diagnosis and management of poisoned patients through our diverse curriculum and training environments.  This fellowship is approved by the Accreditation Council for Graduate Medical Education (ACGME).

Program Basics

The goals of this program are to provide a broad-based and in-depth experience that includes:

  • Acute care medical toxicology
  • Management of the critically-ill poisoned patient
  • Occupational toxicology
  • Environmental exposures
  • Addiction Medicine
  • Poison center management
  • Opportunity and time for independent research

Curriculum Highlights

Bedside Consultation Medical Toxicology Service

At SUNY Upstate, we have a bedside Medical Toxicology consult service that currently sees bedside consults at Upstate University Hospital and Golisano Children’s Hospital. Through this experience, fellows gain expertise in the toxicological physical exam and management of many common xenobiotic overdoses. Our consult service also sees complicated patients in our intensive care units to explore the toxicological differential in patients without confirmed exposures. All patients are seen during business hours by both a fellow and a board-eligible or board-certified Medical Toxicologist.

Poison Center Consultant Call

Medical Toxicology fellows participate in consultant call for the Upstate New York UNY) Poison Center, with supervision by an attending medical or clinical toxicologist. The UNY Poison Center has a broad catchment area covering 54 counties. This is a 24-hour service in which fellows gain experience with phone consultations with both patients at home as well as health care providers. We provide over-the-phone toxicology consults for hospitals across New York State, particularly for hospitals without bedside Toxicology services. Through this experience, our fellows are exposed to a diverse array of toxins - from household toxins, occupational toxins, poisonous plants, envenomations, and pharmaceutical agents. This experience prepares the fellows to work as a Poison Center Consultant in the future.

Additionally, our fellow offices are housed in the UNY Poison Center and fellows work closely with our Specialists in Poison Information, Clinical Directors and Medical Directors. Our fellows spend time answering the phones for the poison center hotline where they gain experience with managing patient exposures in both the home setting and initial healthcare setting.

Further information regarding the UNY Poison Center can be found here:


Addiction Medicine

SUNY Upstate has both a Medical Toxicology consult service as well as an Addiction Medicine consult service. Our fellows rotate through our Addiction Medicine consult service as well and gain experience with complex addiction patients. Our fellowship director, Dr. Ross Sullivan, is dual board-certified in Medical Toxicology as well as Addiction Medicine. Thus, we provide a unique educational experience for our fellows through bedside addiction consults as well as at an Addiction Medicine clinic.

Medical Toxicology and Occupational Toxicology Clinic

We have a weekly, in-person Medical Toxicology clinic on campus that is staffed by Medical Toxicology fellows and attending Medical Toxicologists. This allows for exposure to chronic occupational exposures and chronic poisoning. We also see many patients with concern for heavy metal poisoning.

Medical Toxicology Board Preparation

Our program is committed to preparing fellows for succeeding at the Medical Toxicology Board Examination which is held every two years for graduating fellows. Fellows are encouraged to attend the American College of Medical Toxicology’s board review course which is held biannually. Fellows will also receive individualized board preparation sessions from fellowship leadership on a biweekly basis. In addition, we have a weekly email-based curriculum to highlight historical toxins, occupational toxins, and important toxicological structures. We currently have a 100% first time pass rate for graduating fellows taking the medical toxicology board exam.

Teaching Opportunities

The UNY Poison Center hosts a toxicology rotation for medical students, pharmacy students, residents and fellows from SUNY Upstate and also outside institutions. As part of our toxicology fellowship, fellows are expected to participate in and lead teaching rounds with the rotators based on poison center cases and bedside consultations. This rotation also includes weekly simulations which provides the fellow with the opportunity to create new simulations and practice running a toxicology simulation for more rare toxins. Every Thursday, the fellow participates and eventually leads a case-based conference for our rotators.

Journal Club

We host a weekly journal club with our toxicology rotators which is fellow led, reviewing high yield articles from a broad range of journals, often including Clinical Toxicology and the Journal of Medical Toxicology. This inspires fellows to incorporate weekly journal review into their practice and generate research ideas. In addition, we hold out of hospital journal clubs with fellows and attendings to discuss controversial topics and historical literature. We collaborate with other regional toxicology fellowships to review literature published monthly in high impact toxicology journals.

Didactic Curriculum

Our didactic curriculum was revamped in 2023 and is a combination of textbook chapter review and primary literature review. Fellows meet with faculty on a weekly basis to review topics in toxicology, consisting of chapters from Goldfrank’s Toxicologic Emergencies, paired with landmark peer-reviewed articles. Our curriculum spans 18-months, thus fellows will cover high yield material more than once. To support our didactic curriculum, we also invite outside speakers to enhance certain topics such as Occupational Medicine. When possible, our fellows are encouraged to attend additional training in Radiation Medicine in Tennessee, and also visit the Cornell Poison Garden for practice in poison plant identification.


Fellows are required to complete a scholarly project by the end of Fellowship and are encouraged to participate in research projects. We have administrative support for research and ample opportunities for academic writing and research mentorship. As a second-year fellow, the month of July is reserved for expanding upon research projects. Our faculty are very academically productive. A sampling of publications can be found on our poison center website here:
