Group leadership
Professor Ljiljana Fruk
Ljiljana obtained her International Baccalaureate from United World College of the Adriatic (Italy), studied chemistry at the University of Zagreb and then went on to explore advanced biospectroscopy (PhD at the University of Strathclyde, Glasgow) and DNA structuring and artificial enzyme design (postdoc in the group of Prof. Niemeyer at the Technical University of Dortmund).
She was a group leader at Karlsruhe Institute of Technology, Germany, for 7 years before joining the Department of Chemical Engineering and Biotechnology in 2015. She is a Professor of BioNano Engineering and teaches courses in Bionanotechnology, Chemical Product Design, and Engineering Ethics.
She very much enjoys science fiction books, any activity that involves walking, nature and gardens, dreaming up new chocolate designs, and devising creative strategies to make science more approachable and people around her more curious about life, the universe and everything.
Helen Marshall - PA
Helen Marshall provides administrative support for the NanoFlash project and is Personal Assistant to Professor Ljiljana Fruk. She brings over two decades of experience as a Senior Teaching Office Administrator from the Cavendish Laboratory, where she played a key role in supporting undergraduate teaching and student administration. Known for her practical approach and commitment to helping others, she enjoys being part of the teams that make teaching, research and collaboration run smoothly behind the scenes.
Post-doctoral researchers
Dr Ishtiaq Ahmed
Ishtiaq obtained his PhD degree in 2007 from the University of Paderborn, Germany, under the supervision of Prof. Karsten Krohn with a thesis on the study of enantioselective epoxidation, asymmetric reduction, and synthesis of bioactive oligomeric flavonoids. He carried out his postdoctoral research in the same group, working on the synthesis of chiral macrolide building blocks from sugar and the synthesis of anthrapyran antibiotics.
In 2010, he moved to the Fruk group at Karlsruhe Institute of Technology (KIT) and worked on the design of photoswitchable, multifunctional linkers for nanoparticle, DNA, and protein modification. In 2014, Ishtiaq joined the group of Prof. Niemeyer at the Institute of Biological Interfaces (IBG-1) in KIT, where he was involved in different projects including the synthesis of different fluoresceins, biotinylated substrates, acridine-based DNA-intercalators and the synthesis of organic molecules used for the modification of silica nanoparticles, proteins and DNA-origami.
In 2020, he rejoined the Fruk group to work on the development of membrane-adherent, light-sensitive nanodevices capable of neuronal activation and the use of surface-immobilised antibodies to target specific cell phenotypes. His research interests focus on the development of new synthetic methods and the synthesis of multifunctional organic compounds used for different biological applications.
Dr Andrew Baker
Drew received his BSc from Michigan State University (MSU) in Biochemistry and Molecular Biology. Where he studied the origin of life chemistry with Dr Robert Root-Bernstein, he thereafter moved into biophysical research with Dr Matthew Comstock, studying electronic bacteria and optical tweezers.
Throughout this time, he also collaborated with Adam Brown, a bio-artist, who helped create [Ir]reverent: Miracles on Demand. In his spare time, he enjoys art, climbing, and running. He completed his PhD in 2024 under the joint supervision of Ljiljana and Daniel Muñoz Espin. He is a co-founder of Senesys Bio.
Dr Alex Evtushenko
Alex completed his MEng degree at the Department of Chemical Engineering and Biotechnology and his PhD in 2026. He is working on remodelling the pancreatic tumour microenvironment using protein nanocarriers.
In his free time, he enjoys hiking and playing guitar.

Her PhD research is focused on functionalisation of nanodiamonds to be used as intracellular quantum sensors. Outside of the lab, Abbie enjoys dancing and teaching ballet as part of the Cambridge University Ballet Club.
Oriol Colomer-Ferrer
Oriol is a PhD student in the University of Cambridge Sensor CDT program. He is a Hitachi-funded student working on the development of bioinspired nanozymes, in particulary flavin-hybrids. He holds a BSc degree in Nanoscience and Nanotechnology from the Autonomous University of Barcelona (UAB) and an MSc in Biomedicine from the University of Barcelona (UB).
Oriol enjoys inspiring walks under the trees, a good song when it rains, and board game nights with friends.
Alexander Corbett
Alexander comes to us from the University of Toronto, where he did his MSc in Chemistry, working on stimuli-induced antibiotic delivery hydrogels. He previously studied at The University of British Columbia, where his BSc work in Biochemistry and Molecular Biology involved trying to isolate and characterise exosomes with super-resolution microscopy.
He has joined the BioNano Engineering group to indulge his creativity and do cool things with DNA. Outside of the lab, Alexander enjoys Orienteering, lamenting over the lack of snow in Cambridge, making a colossal – albeit temporary – mess of his kitchen, and cinnamon buns (which we all sometimes get to taste!).
Dina Haddad
Dina received her BEng in chemical engineering from the University of Nottingham, during which she completed an industrial year in environmental consultancy. She entered the world of nanotechnology during her MPhil, at the University of Cambridge, where she worked on the synthesis of magnetic nanoparticles for medical applications.
She is now a PhD student, co-supervised by Dr Ljiljana Fruk (CEB) and Dr Richard Mair (CRUK Cambridge institute), working on the development of nanocomposite materials for the extraction of cell free DNA from urine for subsequent analysis. Outside of the lab, you will find Dina playing any piano she spots. She is also the captain of the university pole sports team.
Pui Ting Ho (Adrian)
Adrian studied MEng Material Science and Engineering with Biomaterials at the University of Manchester, where he discovered his love of bionanomaterials. He then joined the NanoDTC here at Cambridge and graduated with an MRes in Nanoscience and Nanotechnology.
Supervised by Ljiljana and Prof Laura Itzhaki (Department of Pharmacology), he is now working alongside Dr Andrew Baker on creating protein-degrading nanoparticles as a new senolytic for chemotherapy-induced senescence in cancer. When he is not working in the lab, he spends most of his free time playing guitar and developing his photography skills.
