M.ASc. in Biomedical Engineering, McMaster University
NSERC Post-Graduate Scholarship (2022-2025)
Hi! I’m Jonathan Dorogin. I’m a PhD student in the joint Biomedical Engineering program between University of Oregon and Oregon State University, working under the supervision of Dr. Marian Hettiaratchi. Prior to joining the Knight Campus and Dr. Hettiaratchi’s lab, I did a master’s in Biomedical Engineering in Dr. Todd Hoare’s lab at McMaster University, focusing on ultrasound triggered drug delivery for cancer applications which was spun out into a startup called Pharmasonica. I’ve also worked in industry and helped to develop a bio-lubricant for people suffering from osteoarthritis. In my spare time, I like to stay active by playing basketball, ultimate frisbee, and doing pilates. I also like to paint and cook. I’m a big Toronto Raptors fan, and enjoy watching cooking shows and cartoons.
David Frey
Graduate Student (Bioengineering)

Promising Scholar Award (2022)
Hi Everyone! My name is David Frey and I’m a PhD student in Dr. Hettiaratchi’s Lab where I focus on the development of immunomodulatory strategies for spinal cord injury recovery. Prior to arriving here at the Knight Campus, I studied Biomedical Engineering at Georgia Tech where I trained in Dr. Roy’s Lab and the Marcus Center for Therapeutic Cell Characterization & Manufacturing. I’ve had the opportunity to help develop Organ-on-Chip platforms, look at immunomodulation in the context of bone fracture repair, and characterize cell therapy potency. When I’m not in the lab I like to go bouldering with my roommates, cross-up people on the soccer field, and critique craft breweries!
Alycia Galindo
Graduate Student (Bioengineering)
B.S. in Chemical Engineering with Bioengineering Concentration and Chemistry Minor, University of New Mexico
Hello! My name is Alycia Galindo. I am a PhD student in the Bioengineering program at the University of Oregon Knight Campus. I recently graduated with my Bachelor of Science in Chemical Engineering while concentrating in Bioengineering and minoring in Chemistry from the University of New Mexico. My undergraduate research in the Brinker Lab included fabricating and characterizing mesoporous silica membranes for dehydrogenation for the Center for Innovative and Strategic Transformation of Alkane Resources. Outside of lab, I enjoy drawing, swimming, and exploring Oregon!
Madeline Martin
Graduate Student (Bioengineering)
B.S. Biochemistry and Molecular Biology/Biotechnology with a Minor in Computational Mathematics, Science and Engineering, Michigan State University
Hi! My name is Madeline Martin and I’m a Bioengineering PhD student in Dr. Marian Hettiaratchi’s Lab at the Knight Campus. In my undergrad, I worked on characterizing ionophores responsible for the uptake and transport of lanthanides in Methylobacterium extorquens AM1 for biotechnology applications. Then, I participated in the Rosetta Commons Post Baccalaureate Fellowship Program and learned the Rosetta Commons software platform for biomolecular modeling and developed broadly useful computational methods to assess the uncertainty in dose-response experiments using R and Stan. I enjoy rock climbing, hiking, skiing, camping, and chilling with my cats!
Malvika Singhal
Graduate Rotation Student (Biochemistry)
B.S. in Bioengineering with Minor in Mathematics, University of California - Berkeley
My name is Malvika Singhal, and I am a first-year graduate student in the Department of Chemistry and Biochemistry at the University of Oregon pursuing a PhD in Biochemistry. Before arriving in Oregon, I had the privilege of contributing to a variety of inspiring research questions such as how taste preferences evolve in ancestrally microbe-feeding flies and how neutralizing antibodies can be detected using chemically conjugated protein-DNA complexes. Outside of the lab, I am passionate about cooking, lifting, writing, and contributing to efforts that make STEM an inclusive space.
Justin Svendsen
Graduate Student (Biochemistry)
B.S. in Biochemistry, Western Washington University
Hello! I am Justin Svendsen, a PhD student in the Biochemistry degree program here at the University of Oregon. Prior to joining the Hettiaratchi lab, I received my Bachelor of Science in Biochemistry from Western Washington University. My undergraduate research experience involved rational design and characterization of sortase enzymes, membrane-bound proteins on the surface of gram-positive bacteria that play an integral role in bacterial virulence, with modular substrate recognition for applications in human health and protein engineering. This work culminated in generating the first crystal structures of a sortase non-covalently bound to its recognition motif, providing insight into the mechanism by which gram-positive bacteria invade host cells and informing further characterization of sortases as protein engineering tools. Outside of the lab, I like to keep in touch with nature by pursuing my passions in sea kayaking, mountain biking, alpine hiking, and beekeeping.
Yan Carlos Pacheco

Promising Scholar Award (2021)
Hi! I’m Yan Carlos Pacheco and I was born in Havana, Cuba. I’m a Ph.D. student in the joint Bioengineering program between the University of Oregon and Oregon State University, working in both Dr. Nick Willett’s and Dr. Marian Hettiaratchi’s laboratories at the Knight Campus. Before coming to Oregon, I did my Bachelors of Biomedical Engineering at The University of Florida in which I worked in Dr. Kyle Allen’s laboratory for four years. As an undergraduate, I got hands-on experience with designing histological experiments for knee osteoarthritis. I briefly worked on characterizing synovial fluid with magnetic particle translation; a novel technique developed in our lab. Lastly, I also worked on developing Matlab scripts to process and quantify synovial tissue changes at the joint level. In my spare time, I enjoy cuddling with my two cats, Norman Rockwell and Lisa Newcarr. Beyond my two children, I enjoy baking, cooking, hiking, puzzles, swimming, and film photography just to name a few.
