Muhammad Afzal, MD, MS

Muhammad “Zubair” Afzal, MD, MS

Medical School: King Edward Medical University, Pakistan

Residency: University of Illinois Urbana-Champaign

About me: I graduated from King Edward Medical University, Pakistan. After completing my internal medicine residency from Grand Rapids Medical Education Partners/Michigan State University in 2014, I did a chief year from the University of Illinois at Urbana Champaign in 2015.

I joined the Department of hospital medicine at Dartmouth-Hitchcock Medical Center in 2015 and have been an assistant professor with the Geisel School of Medicine ever since. I am also with the On-Doctoring program at Geisel, precepting first- and second-year medical students before their clinical years. I was awarded a 2019 Dartmouth-Hitchcock Emergency Medicine Residency Consultant of the Year Award.

I completed a masters program in pharmacology and clinical research from The Ohio State University in 2017, and have been actively involved in clinical and translation research in Oncology at both the Norris Cotton Cancer Center at Dartmouth-Hitchcock, and the Cancer and Hematology Center of West Michigan, Grand Rapids. I have a particular interest in experimental therapeutics and clinical trials. I have several first-author publications. I have been a scientific reviewer for the Journal of hospital medicine and was one of the top reviewers for the year 2018.

Outside of work, I like to spend time with my family, to travel and try out different cuisines. I play badminton, squash sometimes, and have been trying to learn skiing for the last two years. I live in Hanover, NH, with my wife Tayyaba and five-year-old daughter Ayra.

Natasha Dhawan, MD

Natasha Dhawan, MD

Medical School: St. George’s University School of Medicine, Grenada

Residency: Mercy Health - The Jewish Hospital

Fellowship: Palliative Care, Dartmouth-Hitchcock Medical Center

About me: I grew up in Toronto, Canada, graduated from St. George's University School of Medicine in Grenada, residency in Cincinnati, Ohio, and Hospice and Palliative Medicine fellowship at Dartmouth-Hitchcock. Basically, I’ve moved around quite a bit throughout my training and experienced the benefits of working in multiple healthcare systems and especially in different parts of the US. Coming to Dartmouth was an easy decision, the people were genuinely kind and the emphasis on prioritizing patient care was evident. These values are exemplified throughout the institution and definitely in the hematology and oncology department.

My clinical and research interests include integrating the principles of palliative medicine and oncology, with an emphasis on gender and racial disparities. I hope to engage patients in shared decision-making and optimize their quality of life during treatment and afterward.

Lebanon is definitely different than most of the other places where I’ve lived. There are endless outdoor activities to engage in, throughout the year. I try to go home to see my family in Toronto as much as possible, barring any pandemics!

Sam Ibrahim, DO

Samer “Sam” Ibrahim, DO

Medical School: Alabama College of Osteopathic Medicine

Residency: Stony Brook Southampton Hospital

About me: I was born in Alexandria, Egypt but moved to the U.S. when I was young. I completed my high school and undergraduate education in Massachusetts and then went on to complete my medical education at the Alabama College of Osteopathic Medicine. I completed my internal medicine training at Stony Brook Southampton Hospital on Long Island, NY where I also served as chief resident.
I am looking forward to starting my hematology/ oncology fellowship training at Dartmouth-Hitchcock Medical Center. Pursuing a career in heme/onc has been a goal since high school after multiple family members succumbed to long, difficult battles with cancer. Working at Dartmouth-Hitchcock has also been a particular dream of mine since a small research opportunity during my undergraduate education brought me here. Since then, I longed to return and one day complete my training here. Now, I am overjoyed to have the opportunity to be back in such a great academic institution where I can complete my education, training and research. I also look forward to helping real patients battle cancer as my family members once did. I am also excited to be back in New England, where I grew up.
When I am not in the hospital or clinic, I like to spend time with my wife and our baby daughter. I also enjoy cooking, trying new foods and cuisines, traveling, and reading.


Odeth Barrett-Campbell, MBBS

Odeth Barrett-Campbell, MBBS

Medical School: University of the West Indies, Jamaica

Residency: SUNY Downstate Medical Center

About me: Greetings everyone! My name is Odeth and I am from the beautiful mountainous island situated in the north of the Caribbean Sea. I am speaking of Jamaica. My interest in Hematology/Oncology stemmed from my medical school training at the University of the West Indies in Kingston, Jamaica. This interest piqued while working there and during residency at the SUNY Downstate Medical Center in Brooklyn, New York.

My interests include GU Oncology, cancer health disparities and cancer survivorship. Having completed a year of Hematology/Oncology fellowship training at DHMC I can truly say that there are many opportunities for career development and professional growth. I also appreciate that the faculty is supportive and fellows have a good work-life balance.

My husband and I have truly enjoyed the scenic and natural beauty that NH is renowned for!

Lukas Emery, DO

Lukas Emery, DO

Medical School: University of New England College of Osteopathic Medicine

Residency: Dartmouth-Hitchcock Medical Center

About me: Hello everyone! As many of you already know, my name is Lukas Emery (Luke for short). I was born and raised in a small town in northern Maine and spent most of life there; this was up until I decided to be adventurous and travel about an hour south for college. I attended the University of Maine where I earned a bachelor's degree in Microbiology and spent time working in the laboratory at a local hospital. From there, I ventured even farther south to attend medical school at the University of New England which ultimately led me to DHMC for my Internal Medicine training. I have to say that this was one of the best decisions of my life; I have had the opportunity to work, learn, research, and teach alongside some of the most amazing people and doctors I have ever met. DHMC feels like home and I am so honored and excited to stay here for my hematology/oncology fellowship.

Currently, I am living in Lebanon with my amazing fiancé Sam; we have a wonderful 2yr old son named Damon and a slightly above average cat named Marvin. Outside of medicine, we truly value time with our family/friends and try to make it home whenever we have the opportunity to do so. In our free time we try to stay active and enjoy playing/watching sports (LOVE all Boston sports teams), hiking, skiing, swimming, boating, and trips to the beach in the summer (Higgins Beach in Scarborough, ME is our favorite). We also love to travel and enjoy day/weekend trips to the nearby cities for good food/drinks and shopping.

Ultimately, I couldn't ask for a better place to raise a family and continue my medical training. I'm honored to be here as a DHMC hem/onc fellow!

Heather Wright, DO

Heather Wright, DO

Medical School: University of New England College of Osteopathic Medicine

Residency: University of Vermont Medical Center

About me: Hello! My name is Heather and I am originally from Oxford, MA, a small town in central Massachusetts. After graduating high school, I studied biomedical engineering at Worcester Polytechnic Institute. I then moved to Boston where I spent three years working in a research laboratory at Brigham & Women’s Hospital before entering medical school at the University of New England College of Osteopathic Medicine (UNECOM) in Biddeford, Maine. After UNECOM, I completed residency in Internal Medicine at the University of Vermont where I gained a profound appreciation for the diagnosis and management of both hematologic and oncologic disorders. I graduated from Internal Medicine residency in 2018 and stayed on for a chief resident year. I have since matched and started fellowship in Hematology/Oncology at Dartmouth-Hitchcock Medical Center. I can say with little hesitation that the first year of fellowship has flown by and without a doubt that Hematology/Oncology is my calling. While my career plans are still yet to be determined, I have appreciated the learning environment that is fostered at DHMC. I am currently working with one of the GI oncologists on developing a protocol that explores a dynamic dosing algorithm for patients receiving FOLFOX chemotherapy. While fellowship keeps me busy, in my spare time I enjoy hiking and biking. My husband and I have two dogs (who also love to hike) as well as a toddler at home who is just learning to appreciate the outdoors!


Alexandra Donovan, MD, MPH

Alexandra Donovan, MD, MPH

Medical School: University of Arizona College of Medicine - Phoenix

Residency: Dartmouth-Hitchcock Medical Center

About me: I grew up in the beautiful mountains of Vail, Colorado and will always consider the mountains home. I later earned my Bachelor's degree in Molecular Biology from Colgate University in upstate New York, where I raced on the ski team, sang in a co-ed a cappella group and served as an EMT for the county ambulance. I dreamed of becoming a doctor since my father passed away from melanoma when I was seven years old, and I pursued my dual MD/MPH degree at the University of Arizona College of Medicine in Phoenix. I met my husband in medical school, and we were fortunate enough to couples match at Dartmouth-Hitchcock for my Internal Medicine and his Emergency Medicine Residency. In fact, he proposed on Match Day as we announced our match at Dartmouth!  Throughout my residency, I grew very close to the Hematology & Oncology faculty and was so grateful to stay at DHMC for my Hematology-Oncology Fellowship!

I have dreamed of a career in Oncology since I met my dad’s Oncologist years ago and admired the relationship he kept with our family, even after my father passed. I love working with cancer patients and their families at such a sensitive time in life. My clinical and research interests are focused on improving quality of life and improving the “Cancer Experience” for patients, both physically and emotionally. I hope to be a general Hematologist & Oncologist in a community practice upon graduation.

My Husband, 2yr old Addie, Golden Retriever and I welcomed baby #2 in July 2020! We love enjoying the incredible outdoor opportunities in NH/VT, particularly the skiing, hiking, swimming, camping, fishing, biking, kayaking, farmers markets, and delicious microbreweries.

Parth Shah, MD

Parth Shah, MD

Medical School: Smt. NHL Municipal Medical College, India

Residency: Lahey Hospital and Medical Center, Tufts University

About me: I grew up in India and completed my medical school there while developing an interest in molecular genomics which led to my first industrial exposure. After a brief stint in industry, I completed my residency at the Lahey Clinic  and was super excited to continue my fellowship in the region at Dartmouth. I love the snow and all 4 seasons though the rest of my family doesn’t necessarily agree! I enjoy hiking, running and playing tennis as well as chess!

Allison Smith, MD, MPH

Allison Smith, MD, MPH

Medical School: University of Arizona College of Medicine – Phoenix

Residency: Mayo Clinic Arizona

About me: I grew up outside of Chicago and moved to New England to attend college at Dartmouth. I became interested in global and public health and ultimately pursued an MPH degree after graduation, where I specialized in chronic disease and cancer epidemiology. I moved out to sunny Arizona and worked for the state public health department as an epidemiologist for community nutrition programs before going to medical school and completing residency in the Phoenix/Scottsdale area. The heat was too much for me though, and I was happy to return to Dartmouth for my hematology/oncology fellowship! When I am not at work I enjoy reading, hiking, traveling, walking my two big sweet dogs, and exploring beautiful New England with my family!
