Lab Members



PBollykyPaul Bollyky, MD, PhD – 2013

The fearless leader of the matrix immunology research army.   Dr. Bollyky is an Assistant Professor in the School of Medicine Division of Infectious Diseases and also the Department of Microbiology and Immunology.  Furthermore, he is a faculty member in the Stanford Immunology Program.

Paul is from Stamford, CT and went to college at Columbia University in New York City.  He did his Ph.D. at Oxford University under Dr. Eddie Holmes. He went to Harvard Medical School for his M.D.  He did medical internship and residency at  Brigham and Women’s Hospital and then Infectious Disease fellowship at the University of Washington.  He completed a post-doctoral fellowship under Dr. Jerry Nepom at the Benaroya Research Institute.  He was appointed to the Stanford  faculty in 2013.


HeatherHeather Ishak – 2014

Heather is the lab manager for the Bollyky lab.  She is the go-to person to handle questions about protocols and all lab related business.  She also assists in the diabetes and wound healing research.

Heather has a BS in Animal Science from UC Davis (2005) and an MS in Conservation Biology with a molecular emphasis from San Francisco State University (2007).   Previously, she worked as a lab manager for the Mueller lab in the Integrative Biology department at the University of Texas from 2007-2012.  Her previous research has included blood parasites in hawks and owls, coevolution of leaf-cutter ants including whole bacterial community analysis and genome assembly.


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.



HedwichHedwich Kuipers2014

Hedwich straddled the Bollyky lab and Steinman lab for several years but is now a full-time Bollyky lab researcher.  She is investigating autoimmunity from a neuronal background with a research focus in Multiple Sclerosis.   Hedwich is also researching IL2 and heparinase.


NadineNagyNadine Nagy – 2014

Nadine  finished her postdoctoral research at Benaroya Research Institute in Seattle 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.



LizBurgenerElizabeth Burgener, MD  -2016

Liz is an MD and a pediatric pulmonology fellow who is interested in pseudomonas and CF.   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.




JolienJolien 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 explore and 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.

CarlosWebsiteCarlos Medina – 2015

Carlos is an Immunology Student who rotated in the lab during Winter Quarter 2015.  During his rotation, Carlos worked on cell signaling projects with Shannon Ruppert.  Since joining the lab, Carlos has shifted his interest to investigate the role of IL-10 in inflamed lung tissues. However, Carlos is also partnering up with Hedwich on investigating how heparin/HS chains impact immune cells.


PaytonPayton Marshall – 2014

Payton is a MSTP student and also in the Immunology PhD program.  During the summer in 2014, Payton rotated in Bollyky lab where his research focused on airway hypersensitivity. He joined the Bollyky lab in 2015 and is working on how 4-Mu affects antigen presentation.  He is also investigating 4-Mu impacts on organ transplants.
