mike_kratchovilMike Kratochvil – 2016 

Mike is a shared post-doc between the Bollyky lab and the Heilshorn lab at Stanford who is straddling the line between immunology and bio material engineering.  Mike is a Chemistry PhD from University of Wisconsin and we are excited to see how his skills can challenge our thinking about immunology and our hyaluronan projects.

LizBurgenerElizabeth Burgener, MD  -2016

Liz is an MD and a pediatric pulmonology fellow who is interested in pseudomonas and Cystic Fibrosis.   In our lab, Liz is studying how Pf phage contribute to the disease burden in CF.   She uses qPCR to correlate sputum phage counts with clinical outcomes in CF.

Ievgen Koliesnik -2017

Ievgen was born in Ukraine in its metallurgical capital – Krivoy Rog. He graduated from Kiev National University with a Master’s in biochemistry. After that, he moved to the lovely city of Jena in Germany where he fell in love with immunology. He became fascinated with how different cells of immune system interact with each other to generate an immune response. His special interest  in the Bollyky lab is the “non-immune function” of immune cells. He is happy to be a part of matrix immunology lab and work with the wonderful team of scientists. His long term goal is to see how his research contributes to the  treatment of autoimmune diseases. His interests outside of the lab are traveling, swimming and martial arts. Ievgen hopes that his time spent at Stanford will be very exciting and productive.

Jonas D Van Belleghem – 2018

Jonas completed his PhD research at Ghent University, where he studied the interaction of bacteriophages and the human immune response. During his PhD, Jonas showed that certain Pseudomonas aeruginosa and Staphylococcus aureus phages induce an immune response and have a tendency to induce anti-inflammatory properties.During his research, Jonas developed a profound interest in phage biology and phage therapy, more specifically in the interaction between phages and the mammalian host. Jonas is looking forward to further elucidate the interaction of phages with the human immune response, and the potential impacts this could have on phage therapy or human health.

Christiaan Robert de Vries, MD, PhD- 2018

Christiaan is an Infectious Disease Fellow who will be examining the use of vaccines targeting Pf phage to prevent Pseudomonas infection. He completed his MD and PhD at Rutgers University and went on to Internal Medicine Residency at the Mount Sinai Hospital before coming to Stanford for fellowship.



Nadine Nagy – 2014

Nadine  finished her postdoctoral research at Benaroya Research Institute and then moved to join the Bollyky lab.  Her research is focused on the role of hyaluronan during development and progression of type 1 diabetes (T1D).  She is helping to develop the drug 4-MU for clinical trials.

Dr_Gernot_Kaber_2013Gernot Kaber – 2014

Gernot has joined the Bollyky lab after a working  for the Benaroya Research Institute.   Gernot is involved in practically every ongoing research project in the Bollyky lab, because he knows how to do EVERYTHING.



Dung Lam- 2017

Dung  takes care of our vivarium and genotyping and is working on projects related to 4-MU development with Nadine Nagy . She graduated from San Jose State University with a BSc in Biochemistry and hopes to attend graduate school.




Jolien Sweere – 2013

Jolien Sweere is a PhD candidate in Stanford University’s Program in Immunology. Her work currently focuses on elucidating the molecular mechanism behind the immune suppression observed in chronic biofilm infections of the pathogen Pseudomonas aeruginosa. Jolien uses flow cytometry, fluorescent microscopy, gene expression analysis and other techniques to investigate how individual biofilm components work together to suppress dendritic cell activation and antigen presentation. The ultimate goal of her research is to develop therapeutic strategies to disrupt this biofilm-mediated immune inhibition.

Growing up in the Netherlands, Jolien pursued a BSc degree in Liberal Arts & Sciences at University College Utrecht, graduating summa cum laude in 2009. She obtained an MSc degree in Infectious Diseases and Immunology from Utrecht University in 2011. During her Master’s program, she worked in the lab of Rob Willems at University Medical Centre Utrecht, Utrecht, the Netherlands, and the lab of Vijay Kuchroo at Brigham and Women’s Hospital, Boston, MA, USA. Before starting her PhD program at Stanford University, Jolien was a visiting student researcher in the lab of Eugene Butcher at the Veteran’s Affairs Hospital in Palo Alto, CA, USA.

Carlos Medina – 2015

Carlos Medina is a PhD candidate in the Immunology program at Stanford University School of Medicine. His work currently focuses on understanding the mechanisms of long-term tissue-specific tolerance in allergic asthma. In tandem, he is working on ways of utilizing extracellular matrix proteoglycans to promote these tolerogenic lung responses, targeting the immunological root causes of allergic asthma. Carlos is a Ford Foundation fellow and a Stanford DARE fellow and serves the community through his role as President of the Biomedical Association for the Interest of Minority Students.

PaytonPayton Marshall – 2015

Payton is a MSTP student  in the Immunology PhD program.   He came into the lab with a strong background in engineering and microfluidics in particular.  Payton’s research focuses on hyaluronan, pericellular matrix, and antigen presentation.   He is also investigating 4-MU impacts on organ transplants.


Graham Barlow – 2017

Graham is a PhD candidate in the Immunology program at Stanford University School of Medicine.   He is co-mentored by Garry Nolan and is working on the using high-dimensional imaging to study how cells coordinate in their native tissue contexts. He is especially interested in tissue architecture and how this organization induces and breaks tolerance, especially over long time periods.

Medeea Popescu -2018

Medeea is a PhD candidate in the Immunology program at Stanford University School of Medicine. She is co-mentored by Steve Quake and is working to understand how Pf phage impact human immunology in the context of Pseudomonas aeruginosa infection.

Hunter Antonio Martinez – 2018

Hunter is a PhD candidate in the Immunology program at Stanford University School of Medicine. His research interests are to understand the factors that govern how T cells switch between metabolic states upon activation. Specifically, he hope to gain insight on the role of CD44, a promiscuous transmembrane protein involved in cellular adhesion. The inputs CD44 relays to a T cell at various stages of an immunological campaign has ramifications for both immunometabolism as well potential therapeutic interest.


Naomi Haddock is a graduate student in the Immunology Program at the Stanford University School of Medicine. Naomi is currently rotating in the Bollyky lab and is interested in using both experimental and computational techniques in infectious disease immunology research.

Svenja Zihsler- 2018

Svenja is a  visiting graduate student.  She works with Ievegen and the matrix immunology team studying the effect of heparanase sulfate and T-cells . She recently graduated from Friedrich-Alexander University in Germany with a B.Sc. in Molecular Medicine and is doing an externship in the Bollyky lab during the fall of 2018. Svenja enjoys competitive swimming.


Michelle Bach– 2017

Michelle is a senior majoring in Health Sciences at Stanford.  She joined the lab in early 2017 to help with the Cystic Fibrosis bacterial and phage quantification.  During the summer, Michelle earned a BioX summer grant to pursue more phage and Pseudomonas biofilm related research.
