Research Coordinator

Jeroen Pouwels


Adjunct Professor

Jeroen Pouwels obtained his PhD in 2004 from the University of Wageningen in the Netherlands, after which he did two postdocs in Turku, one at VTT Biotechnology and one at the Turku Centre for Biotechnology. From 2013-2018, Jeroen has run his own research team at the Turku Centre for Biotechnology, which focused on the characterization of the multifunctional adaptor protein Sharpin.

Since August 2017, Jeroen works as research coordinator in the Klefström research group, initially as coordinator of the TEHO project, a Challenge Finland (TEKES) awarded project focusing on adaptive clinical trial design. Jeroen has obtained independent research funding from the Academy of Finland (research project) and K. Albin Johansson Foundation to develop patient-derived tumor explant cultures as a predictive preclinical model for breast cancer and to identify treatments that sensitize breast cancer to immunotherapies. Lastly, Jeroen is involved in the preparation of an investigator-initiated phase I clinical trial in metastatic breast cancer and in spinning out a diagnostic company that utilizes tumour explant cultures.

In his free time Jeroen likes to spend time with his family, he loves traveling all around the globe, and he is a very active stock market investor.

TOPI TERVONEN


Adjunct Professor

Topi Tervonen received his PhD in 2008, in the field of neural stem cells at Neuroscience Center, University of Helsinki. For his post-doctoral training he chose to study molecular cancer biology in Dr. Juha Kleftröm’s group at University of Helsinki. Topi’s work on membrane-anchored serine proteases and cancer has revealed new up- and downstream mechanisms regulating these microenvironment modifying and tumor promoting enzymes. Topi has served as research coordinator since 2014 and also works in Biomedicum Functional Genomics Unit (FuGU) as head of virus services and principal investigator of FuGU/libraries life science infrastructure of GoEditStem infrastructure platform of HiLIFE, University of Helsinki. During recent years, Topi has been actively bringing genome-scale genome editing resources and services into University of Helsinki and he was named the chair of Genome Editing technology platform of Biocenter Finland in 2020. He will also take position as principal investigator in Finnish Genome Editing Center (FinGEEC) core unit of GoEditStem HiLIFE infra platform in 2021. Topi has also worked as part time contractor in Biomedicum Genomics Oy (partially owned by University of Helsinki). Outside work Topi loves sports, music, movies, scientific books, and spending time with his wife and two children.

Doctoral students

Shishir Pant


MSc

Shishir completed his Master’s degree in Molecular biotechnology from University of Helsinki. Currently he is a graduate student in doctoral program in biomedicine and his research focuses on deciphering the oncogenic role of serine protease hepsin in breast cancer. He is particularly interested in how the cancer cell interact with the microenvironment and development of novel therapeutic agents to prevent this cross-talk.  Shishir is also an active board member of biomedical and clinical student council and has been organizing several courses, conferences and various science outreach events. When not in lab, Shishir is either on a football field, hiking or traveling around Europe.

Denis Belitskin


MSc

I received my BSc and MSc in Gene Technology from The University of Tartu (Estonia), where I started in the field of applied virology, and later went on, to study the role of stem cells in liver cancer for my Master`s thesis. My research is focused on novel biological roles of the serine protease hepsin in breast cancer, discovery of mechanisms through which hepsin is providing advantages to cancer cells in growth and survival. I`m working in close collaboration with other members of the team (Topi Tervonen, Shishir M. Pant) and international collaborators in the attempt to target extracellular and intracellular functions of hepsin by using small molecules, which will provide proof of principle that hepsin is an attractive target for breast cancer therapy.

Outside of the lab I`m a great husband, cool father, stock market investor and a beekeeper.

Johanna Anttila


MSc

Johanna Anttila received her MSc degree in Biochemistry from the Molecular and Cellular Biology Programme in University of Oulu and did her Master’s thesis in Klefström lab in 2017. After graduating she has continued her work in the lab as a doctoral student. Johanna aspires to harness oncogene MYC-dependent cancer cell vulnerabilities in the objective of translating our research into benefit of cancer patients. Besides science, Johanna is into various sports including frisbee golf and tennis as well as loves to spend time enjoying music and photography.

Rita Turpin


MSc

Rita Turpin finished her MSc with a major in Human Genetics and a minor in Molecular Biology at the University of Helsinki, and is continuing her work throughout her doctoral studies. Her project focuses on determining the immunocontexture of a novel 3D ex vivo breast cancer model in hopes of opening doors for future immune-relevant synthetic lethal drug combination and biomarker studies. In addition to her own work, Rita has been collaborating with the Tekes-awarded TEHO project which explores Finland’s potential for running adaptive clinical trials in the future.

Rita’s hobbies include singing, board games, and hosting parties.

Computer/data Consultant

Ilida Suleymanova


Ilida has a Master’s degree in computational mathematics, and cybernetics from Kazan Federal University (KFU), Kazan, Russia. During her Masters, she focused on solving mathematical equations using Matlab software. To further enhance her skills, she decided to focus on its implementation in clinical studies, and joined the Neurobiology research group led by Dr. Rustem Khazipov’s at KFU. During her work in this lab, she was involved in developing Matlab-based algorithms for automatized analysis of brain activity in neonatal rats, and the clusterization of spikes of multiunit activity in the immature cortex.
Currently, she is completing her Ph.D. studies at the University of Helsinki. During her Ph.D. study, she quickly learned the necessary skills to perform biological experiments and on the other hand utilized her expertise in programming to develop novel algorithms to quantify large-scale images generated during the experiments.
As part of her long term goal, she wishes to contribute and pursue her career in the field involving mathematical and computational approaches to analyze biological data.
