Monir Bertayli, MSc

Monir Bertayli is a PK-PD consultant at PD-value. Monir has a MSc degree in biomedical sciences (VU Amsterdam) with specializations in cell biology and immunology. He performed internships in the field of oncology and immunology. He joined PD-value in March 2019 as a trainee, and is now working at PD-value as a pharmacometrician, with a focus on the Horizon 2020 QSPainRelief project.

Being a pharmacometrician allows him to achieve his main goal as a scientist, which is to contribute to the search for cures or prevention of disease. He is passionate about expanding his knowledge on health, disease and the working mechanisms of drugs. Monir also values that his work is varied and at the same time is challenging his creativity and insight.

Monir’s broad scientific knowledge ranging from immunology, oncology to pharmacokinetic drug interactions, brings new insights to the PK-PD modeling and specifically helps to understand and apply the various aspects of physiological based PK-PD. Monir is highly motivated and eager to improve himself. He is motivated by a strong curiosity and is creative in finding solutions.

Besides wanting to improve the health of others, Monir is also passionate about improving his own health by regular exercise (running and going to the gym) and having a healthy diet.

Anke Kip, PhD

Anke Kip is a PK-PD consultant at PD-value since March 2019. Anke holds a PhD in Clinical Pharmacology (NKI; Netherlands Cancer Institute) and has a background in molecular biology (Utrecht University). Her PhD research focussed on optimizing treatment regimens against leishmaniasis, a neglected tropical disease. Her PhD work encompassed many stages of (clinical) research including bio-analytical assay development/ validation, laboratory analysis of PK-PD samples and clinical pharmacokinetics and pharmacometrics. After obtaining her PhD, she worked as a program manager at Lygature, where she supported different multistakeholder collaborations.

Anke is passionate about making sense of data and solving complex problems. At PD-value, Anke is most enthusiastic to integrate data of different pre-clinical in vitro and in vivo studies, both PK and PD, to increase insight and understanding of the compound being studied in translation to the clinic. Her specific interest is the modeling of PK-PD mechanisms, especially the immunomodulatory properties of drugs. The combination of science and pragmatism is something she values in her work as a PK-PD consultant.

Outside work, Anke enjoys creative projects, traveling, forest walks and food/drinks with friends and family.

Vincenzo Luca Di Iorio, MSc

Vincenzo Luca Di Iorio is a PK-PD consultant at PD-value since May 2019. Vincenzo has a MSc degree in Physics from the University of Padua (Italy) with a focus on computational cosmology. After his MSc program, he worked at GlaxoSmithKline at the Clinical pharmacokinetics & Modelling and Simulation department. Subsequently he worked as a PhD student at LACDR on the modeling of disease progression and pain response in neuropathic pain.

Vincenzo’s specific interest lies in the optimal design of experiments, mathematical and computational aspects of modelling and scientific research. At PD-value he is also co-responsible for the IT-infrastructure, such as data storage and back-up, with particular attention to data security and data confidentiality.

Vincenzo has extensive mathematical, coding (R, Nonmem, PopED etc) and general computer knowledge. He has a strong scientific curiosity in general, is meticulous and has attention to detail.

Also outside work, most of Vincenzo’s hobbies involve computers and/or coding in one way or another: playing old cRPG videogames and creating user modifications for them, playing chess (against computers), reading sci-fi novels and watching – mostly sci-fi – TV shows.

Yan Zhao, PhD

Yan Zhao joined PD-value June 2020 as a PK-PD consultant. In 2016, he obtained his PhD in mathematics from the University of Milan and Leiden University, on the study of classifications of geometric objects using algebraic equations. Prior to joining PD-value, he worked as a quantitative researcher at Optiver, a financial derivatives trading firm based in Amsterdam, where he developed pricing models and trading strategies.

Yan has a strong mathematical background and practical experience in dealing with complex problems. At PD-value, he works with clients to obtain the most value from their experiments, integrating discovery stage and pre-clinical data to understand the properties of the drugs and the PK-PD mechanisms. He likes working on new challenging problems, learning on the go and will think out of the box for a solution.

Yan also has extensive experience in programming. He has built automations to efficiently extract information from diverse datasets and manage complex models, providing a more streamlined workflow and clearer focus for model development.

In his spare time, Yan loves being out in nature, trekking and solving puzzlehunts with friends.
