Our team

Jonathan Heddle

Fearless Leader.

Antonina Naskalska

My work focuses on developing the of virus-like particles (VLPs) as vaccines, smart drug delivery systems, RNA protecting capsules, and others. Currently I’m particularly interested in developing VLPs originating from feline and human coronaviruses. I’m also involved in investigating VLPs originating from a bacteriophage and “artificial” protein cages and their potential applications.

Dmitry Ghilarov

 I use cryo-EM to develop new antibiotics and overcome antibiotic resistance problem

Dr. Julian David Janna Olmos

Julian works in the Heddle laboratory as a Senior Postdoctoral Fellow who won the prestigious
‘young doctor’ fellowship (mtody doktor in Polish) from the TEAM funding scheme of the Foundation for Polish Science. This extremely generous funding allows Julian to further his career extending his already lengthy experience in advanced biochemistry, biophysics and biotechnology.

Izabela Stupka

I am a PhD student with a background in molecular biology currently working on engineering of artificial protein cages for biomedical applications. I’m particularly interested in different encapsulation strategies and interface modifications of protein cages which can be applied in drug delivery systems. Apart from being a part of Heddle Lab I am also working as a Scientist in nCage Therapeutics company where I further develop TRAP-cage technology for its therapeutical use. 

Łukasz Mazurek

I am a PhD student in Jonathan’s laboratory working on Topoisomerase-targeting pentapeptide repeat proteins. My goal is to understand how those proteins confer resistance for quinolone drugs to bacterial DNA gyrase. Privately I am in love with mountains and any activities connected with them.

Agnieszka Gawin

I am a postdoctoral researcher working in the Azuma subgroup that focuses on a cage-forming lumazine synthase, its redesign, directed evolution, and understanding the assembly process of this enzyme under different conditions. I am primarily involved in research on utilizing lumazine synthase as a container for encapsidic production of proteins that are difficult to express due to their cytotoxicity, misfolding tendencies, or susceptibility to proteolytic degradation.

Agnieszka Kowalczyk

In Heddle Lab I was a member of the Symfonia project (end date April 2021) and the only mathematician so far 🙂 My goal was to understand the geometry of protein cages. Collected and analyzed data during my stay in the lab is the lion’s share in my PhD dissertation at the Jagiellonian University.

Kinga Borzęcka-Solarz

In my work I’m trying to answer the question how designed protein structure scan interact with and effect eukaryotic cells. I`m particulary intrested in artificial protein cages design and production including internal and external modification of cages for its effective delivery to cells and potential application in biomedical research.    

Artur Biela

Macromolecules have been in the center of my interest, since I’ve entered science. Starting from protein crystallography (MX) I finally found my place in the field of cryo electron microscopy (cryoEM). I obtained a PhD degree in Biology at University of Orleans, FR (2013) and in Biochemistry at Polish Academy of Sciences (2014). Since I joined the Heddle-Lab I work with protein nanocages at all stages of their development. Starting from design, and ending up with beautiful 3D reconstructions directly from cryoEM, which are my main focus.

Jan Różycki

I received my Ph.D. in Peptide Chemistry from the University of Gdansk, Poland. I was a postdoctoral fellow in Biochemistry at National Cancer Institute, NIH, USA.  In the Heddle lab, I am interested in the application of peptides in bionanoscience.

Elizabeth Michalczyk

I am primarily interested in topoisomerases and specifically DNA gyrase. I have worked on several projects in Heddle lab involving DNA gyrase from a wide range of organisms including thermophilic archaea and the eukaryotic parasites Plasmodium falciparum and Toxoplasma gondii.

Gerrit Wilkens

I’m a PhD student in the Heddle lab. Primarily I am interested in building novel self-assembling DNA nanostructures and using those to manipulate and control biological matter at the nanoscale. Before joining the lab, I completed my Master’s degree at the University of Hamburg in Germany working on biofilm forming Staphylococci.

Daniel Zakaszewski

A student researcher pursuing his MSc in Biochemistrywith a focus on biophysical chemistry and bioanalysis. I work within the Azuma subgroup, traversing the tortuous pathways of directed protein evolution, which provide a gradual ascent up to the summit: novel, enhanced variants of molecules. My objective is to harness the unfettered potential of protein cages, either natural or artificial, to engineer supercharged enzymes and fluorescent proteins with potential applications in molecular biology and biomedicine. Who knows where the journey might take me?

Dhanasekaran Balakrishnan

I am a Bioinformatician from India and have joined Heddle’s lab as a PhD student. I am using coarse grained molecular dynamics simulation and studying membrane fusion. Before joining Heddle’s lab, I was working in Indian Institute of Science as a Research Assistant and completed a couple of projects.  Outside of the lab, I am interested in photography and traveling.

Zuzanna Pakosz

DNA gyrase is one of the most important targets for antibacterial drugs. However, recently it was found in single cell eukaryotic parasites such as Plasmodium which causes malaria and Toxoplasma which causes toxoplasmosis. Better understanding their structure and mechanism of working could lead to future drug discovery. In my project, I am investigating gyrases from those organisms as well as unusual gyrases from highly thermostable Archaea using biochemical, biophysical and structural methods (cryo EM).

Emilija Napieralska

I was raised in a Polish family in Lithuania. I am pleased to work in Heddle Lab as a Master student. My scientific interests include cell biology and broadly defined synthetic biology. In the Lab I focus on the process of mutated TRAP protein assembly into cage-like structures, as well as their cellular internalization pathways and localization tracking. In my free time I sing in a choir and enjoy contributing to someone’s personal growth.

Dorota Nowińska-Bąk

Administrator in the Heddle Lab, who tries to control grants from a non-scientific point of view, makes lab members’ lives easier by ordering things to the lab and solving minor problems occured within the group. Professionally interested in finance and controlling.

Privately still in love with maths.

Piotr Stępień

Leader of the Origami DNA subgroup with expertise in DNA nanotechnology, membrane mimetic systems, conjugation chemistry and various spectroscopic techniques. Interplay between proteins and lipids always fascinated me so why not add DNA into the mix? Add to this my passion for LEGO bricks and the only answer is bionanoscience! In Heddle lab I am building DNA-protein-lipid nanorobots for enhanced membrane protein control, novel vaccines and structural biology. My other interests include: Electron Paramagnetic Resonance and making music — that’s why they call me true resonance man.

Joanna Szular

I take charge of both laboratory management and experimental work in the Azuma subgroup as a technician and administrator. I joined the group to explore the innovative world of bionanotechnology and to gain experience in administration in the Polish academic system.

Wojciech Czyszczoń

Antimicrobial drug resistance among bacteria is an increasing challenge in clinics. DNA Gyrase is one of the targets for such drugs. That is why, as a PhD student, I focus on investigating gyrase-targeting pentapeptide repeat protein – EfsQnr. This protein was found in genomic DNA of Gram positive bacteria – Enterococcus faecalis, which is a potentially harmful opportunistic pathogen of humans. EfsQnr confers resistance against quinolones – a potent family of antimicrobials. EfsQnr’s biological function and mode of action remains unknown. My aim is to get closer to understanding the mechanism of its interaction with gyrase using biochemical and structural biology methods.

In my spare time I enjoy hiking. I am also interested in ethnography, history and languages.

Dr. Łukasz Koziej

Łukasz is a biochemist who is eager to unravel how large molecular complexes assemble and regulate their dynamic structures to perform biological functions. London was his home for majority of his scientific life. Łukasz obtained his BSc biochemistry degree at University College London in 2015. After graduation, he started his PhD study in Imperial College London where under supervision of Prof. Stephen Curry and Dr. Huw Williams he investigated the role of hibernating ribosomes in M. tuberculosis during latent infection. He completed the doctoral training at the end of 2019 and subsequently moved to Poland to join the Azuma subgroup as one of the startup members. His current goal is to establish his firm foundation in cryoEM technique and expand his knowledge to directed evolution of proteins. Without doubt, Łukasz loves science and pizza.
