Postdoctoral Fellows


Pranatchareeya Chankhamjon

Postdoctoral Fellow
Bio: I recieved my PhD in natural product chemistry from Friedrich-Schiller-University Jena, Germany. I am interested in metabolite profiling, structure elucidation and biosynthesis of small molecules. In the Donia lab, I am highly interested in secondary metabolism of human gut microbiome. In my free time, I play violin, practices yoga and sports. I am fascinated with cooking, painting and jewelry designs.

Yuki Sugimoto

Postdoctoral Fellow
Bio:  I was born and grew up in Japan. I trained in synthetic biology and natural product chemistry and recieved my PhD from Friedrich-Schiller University, Jena, Germany. My research interest is how human microbiome derived molecules impact human health. In my free time, I enjoy dancing Salsa, playing golf, and reading books.

Maria Diarey Tianero

Postdoctoral Fellow
Bio: I trained in marine natural products isolation and structure elucidation at the University of the Philippines with Giselle Concepcion and at the University of Ryukyus in Okinawa with Junichi Tanaka. For my PhD research I studied biosynthesis and natural products engineering at the University of Utah in the laboratory of Eric Schmidt. My research in the Donia lab is focused on small molecules from marine invertebrates and the human microbiome.

Graduate Students


Jared Balaich

Mol Bio Graduate Student
Bio:  I grew up in Colorado and received a B.S. from Brigham Young University in microbial genetics in 2013. In 2015 I received my M.S. degree from the Johns Hopkins Bloomberg School of Public Health after researching a natural product that inhibited the transmission and development of the malaria parasite. In the Donia lab I am interested in researching human microbiota derived small molecules that impact human health. My hobbies include backpacking in the mountains, photography, videogames, playing sports, cheering on the Denver Broncos and losing to my wife in fantasy football every year.

Francine Camacho

QCB Graduate Student
Bio:  I was born and raised in Brooklyn, NY. I received my B.A. in Bioinformatics from Wheaton College, MA. I am interested in developing computational tools to analyze large metagenomic data. During my free time, I enjoy playing sports, binge watching Netflix and dancing.

Shuo Wang

CBE Graduate Student
Bio:  I received my B.S. in Chemical Engineering in 2016 from UC Berkeley, CA. I am interested in applying statistical models and machine learning methods to analyze biological data. In my free time, I enjoy exploring the cities, playing tennis, and playing video games.

Bahar Javdan

Mol Bio Graduate Student
Bio:  I received my BA in Biology from the University of Pennsylvania and did research at the Memorial Sloan Kettering Cancer Center in NYC for a year before matriculating into Rutgers Robert Wood Johnson Medical School and Princeton University’s joint MD-PhD program. In the Donia lab, I am investigating the impact of the gut microbiome on the metabolism of oral drugs, which I hope will pave the way for better individualized therapy. In my free time, I enjoy reading, road trips, and exploring new cuisines.

Jaime Lopez

QCB Graduate Student
Bio:  I received my BSE in chemical engineering from Arizona State University and was an undergraduate researcher at the Swette Center for Environmental Biotechnology. I'm broadly interested in using mechanistic modeling to better understand the inner workings of microbial communities. Currently, my work focuses on the implications of trade-offs in microbial communities and the interplay between drugs and the human microbiome.

Undergraduate Students


Allison Chang

Bio:  I grew up in Saratoga, California and am a member of the Princeton University undergraduate Class of 2018, pursuing a Bachelors of Science and Engineering in Computer Science. I am interested in applying computational techniques to human metagenomic data. In my free time, I enjoy dancing, singing, reading, and watching Netflix/Youtube videos.

Diana Chin

Bio:  I am a senior in the Molecular Biology department, currently conducting my thesis research on antimicrobial molecules native to the human vaginal microbiome.  When I am not in lab, I am likely in Jadwin Gym practicing with the fencing team.  In my free time I like to improvise recipes and explore the outdoors.
