Ganna Panasyuk, PhD,HDR

I have obtained a PhD degree in Molecular biology from the Institute of Molecular biology and Genetics of National Academy of Sciences of Ukraine in Kyiv (Ukraine, 2006). In my graduate studies I was trained in the field of major growth regulator mTOR/PI3K/S6K signalling in the lab of Valeriy Filonenko (Institute of Molecular Biology and Genetics, Kyiv, Ukraine). It is through this graduate training and multiple collaborative visits to Ludwig Institute for Cancer Research in London that my long-lasting interest in the cross-talk between metabolism and signal transduction was ignited. I continued in postdoctoral studies in the lab of Ivan Gout at University College London in UK where I have discovered the novel splice form of mTOR kinase and demonstrated its relevance for cell proliferation. In 2009, I came to France to join the lab of Mario Pende at INSERM. This postdoctoral training has shaped my scientific interest in the mechanisms of metabolic control in physiology and its implication in human disease. In 2013, I have won an INSERM tenure position following a highly competitive international recruitment procedure to develop my research program at the Institute Necker Enfants Malades in Paris. Most recently, in 2019, I have been promoted to an INSERM research director position. Today the research of my team is funded by European Research Council award, French national funding agency (ANR JCJC) and pharma (ADDMedica). I also hold a habilitation degree (HDR) from University Paris Descartes (2015) and currently I am involved in scientific mentoring programs at INEM and different French universities.

Muriel Girard, MD, PhD  

I obtained MD degree from Tours Medical School. Today, I am a practicing pediatrician in the Liver-Gastroenterology department in Necker Hospital. I am diagnosing and treating patients with severe liver disease and specializing in liver transplantation in children. I am convinced that to help these patients we must bring the molecular knowledge of the disease to their bedside. In 2011, I have obtained a PhD degree for my work on the genetic predisposition factors in rare liver diseases. I joined Ganna’s team in 2017 to develop a project aiming to unveil the genetic bases of rare liver diseases.

Catherine Caillaud, MD, PhD

I have obtained MD from Paris Descartes University followed by a certification in Genetics and Habilitation to Direct Research (HDR). Today, I teach as an Associate Professor in Genetics at Paris Descartes University and also head a diagnostic laboratory for lysosomal diseases at Necker Hospital. I am an active member of the Reference Center on Lysosomal Diseases (CRML) directed by Dr Bénédicte Héron in Paris and work in different French committees for the treatment of lysosomal diseases in France. I am a President of the Scientific Committee of the VML (Vaincre les Maladies Lysosomales) association. My basic research is focused on molecular characterization of lysosomal diseases, particularly ceroid lipofuscinoses. One of my achievements is the development of the first diagnosis methods for neuronal ceroid lipofuscinoses in France. Furthermore, I have directed the works on development of therapeutic methods (enzyme replacement therapy, chaperones, and mainly gene therapy) for other lysosomal disorders such as Pompe disease and Sandhoff disease. I joined Ganna’s team to contribute to a project aiming to unveil the genetic bases of lysosomal diseases with unknown etiology.

Marco Hatem Vaquero, PharmD, PhD, Postdoctoral researcher

I obtained my PhD degree in Biomedical Science from University of Alcala de Henares (Spain). My work was mainly focused on understanding the molecular mechanisms that coordinate whole-body glucose and lipid metabolism, involving intra and inter-tissue communication, and the implications of their dysregulation in disease. During this period, I was also part of an emerging biotechnology company, allowing me to collaborate in different projects aimed to find potential applications of new iomaterials in health and medicine. All these experiences and my previous academic training as a pharmacist encouraged me to continue developing my career in translational  research. I joined Ganna’s team in 2020 to contribute to understanding the role of class 3 PI3K signalling in liver metabolism and the consequences of its dysfunction in rare human metabolic diseases.

Yui Shibayama, MD, visiting researcher

I have obtained my MD degree from Asahikawa medical university (Japan). I have been trained as an endocrinologist and a diabetologist. I did some clinical researches especially in the adrenal diseases field. During this period, I got interested in the relationship of steroid hormones with metabolic diseases and I initiated my basic research focused on molecular mechanisms of obesity and metabolic diseases regulated by steroid hormones. I have won JSPS (Japan society for the promotion of science) research fellowship for young scientist and I had an opportunity to join Ganna’s team in 2021. During my stay in MetaboSENS lab I would like to inquire into potential crosstalk between two fascinating signalling hubs of steroid hormones and class 3 PI3K and their contribution to metabolic control.

Chantal Alkhoury, PhD student, supported by FRM

I obtained my MSc degree in cell biology at UPMC. It is during my MSc internship in lab of Francois Rouyer that I was awestruck by the knowledge-gaining powers of genetic models. During this training that I have got the first taste of organismal complexity and the supremacy of biological clocks assuring organismal homeostasis. In 2016, I have joined the team of Ganna to develop a PhD project under her mentorship in which I aim to unravel the complexity of class 3 pI3K signalling in metabolic control in liver.

Nate Henneman,  PhD student, Paris Descartes University 

I obtained my BA from Bates College (Lewiston, Maine 2016). I was trained in the field of vision research at Emory University. My previous research more specifically focused on retinal neurodegenerative disease models and how neuroprotective compounds can be used to prevent functional and morphological damage to the retina. I moved to Paris in September of 2018 to continue my studies in the form of a masters degree at University of Paris Descartes, specializing in molecular biology. In 2019, I have been awarded the MSc degree for my thesis work conducted in Ganna’s team and this allowed me to win the PhD fellowship to continue with my postgraduate studies. I am embarking on the PhD project that aims to discover novel metabolic functions of class 3 PI3K signalling.

Edouard Le Guillou, PharmD, PhD student

I have obtained a PharmD degree from Paris Sud University and currently I’m finishing my Medical biology residency in Paris University at Necker Hospital campus. I have obtained a MSc degree in Cell Biology at University Pierre and Marie Curie defending the thesis project entitled "Mitochondrial dysfunctions in foam cells induced by LDL-cholesterol overload" developed in the lab of Prof. Patrice Therond under the mentorship of Dr. Pauline Gaignard and Dr. Pierre-Hadrien Becker. During my master training I have discovered that cholesterol overload of macrophages in presence of oxidized LDL leads to a mitochondrial oxidative stress with ROS production and glutathione consumption, which is highly relevant to understand the energetic mitochondrial dysfunction in foam cells during atherosclerosis. This first-hand experience in the lab fueled further my passion for translational research. I’m now resident in the Metabolomic and proteomic biochemistry department in Necker Hospital headed by Prof. Robert Barouki. The mission of our clinical department is to provide rapid and reliable diagnostics using state of the art biochemical approaches such as LC-MS/MS metabolomic analyses to the patients suffering from inborn errors of metabolism. I am working hand in hand with Dr. Catherine Caillaud to perfect the diagnostics of severe and still mechanistically largely enigmatic diseases of lysosomal dysfunction also known as lysosomal storage diseases. I have joined Ganna’s team at INEM to develop the PhD thesis project that will combine my three passions: metabolic biochemistry, rare metabolic diseases and signal transduction mechanisms. In my work, I aim to discover yet unknown facets of class III PI3K function at lysosome, it crosstalks with other nutrient sensing pathways in physiology and its implication in lysosomal storage diseases.

Alexis Gadault, Project Engineer

I was graduated in 2016 from the University Paris Diderot with a MSc degree in cellular biology. It was preceded by studies in BTS (Biomedical Analysis) and Licence (Biomedical Research) at ESTBA in Paris. During my undergraduate studies, I did laboratory trainings which ignited my interest in translational research in the domain of immunology. That is why after graduation, as my first job as assistant engineer, I have joined the team of Immunology of Diabetes (Cochin Institute, Paris) where during two years I was instrumental in developing and characterisation of humanised mouse model of type 1 diabetes. Work on this project further matured my interest in biomedical research when we aim to understand the biological processes at molecular level to develop new therapies. I enjoy working as an engineer in a team of researchers as it presents me with the opportunities to contribute to different projects by establishing new techniques, tools and models. I particularly like to integrate data from different approaches that allow developing a better understanding of cellular functions or pathways. So far, I had a great experience with an autoimmune disease and I am looking forward to widen my professional horizons. With this in mind I have joined Ganna's Team to work on a new project that aims to decipher if and how defects in class 3 PI3K signalling in liver manifest in human disease. I am looking forward to apply my expertise in this team and, of course, to growth further professionally.

Konstantina Antoniadou, Project Engineer

I have obtained a Bachelor of Science (BSc) in Biology in 2018 from University of Crete. During my undergraduate studies I completed a 1-year internship in the laboratory of Embryology under the supervision of Dr. Nikitovic. There, I developed an independent project studying the role of biglycan in osteosarcoma cell proliferation and IGF-1 signaling pathway. After graduation, with support of the Erasmus program, I have moved to France for 1-year internship at the Gustave Roussy Institute in the lab headed by Dr. Khaled. During this training, I investigated the mechanisms of immune checkpoint regulation in melanoma. I Entirely enjoyed
my training in France, so I continued in graduate studies and in 2019 I was awarded with a Master in Cellular and Molecular Biology from Sorbonne University. I have completed my master thesis in Stress and Cancer laboratory headed by Dr. Mechta-Grigoriou at Institut Curie. During my 6-month internship, which was supervised by Dr. Mieulet, I studied the translational landscape of MAP3K8/MEK signaling pathway in high-grade serous ovarian cancer. Altogether, my multiple training in different institutes and countries exposed me to various cultures and have helped me to acquire theoretical and experimental knowledge to meet the demands of becoming a research engineer in Ganna’s team. I am looking forward to contribute to different projects that aim to decipher the complexity of class 3 PI3K signalling in metabolic control.





Ines Partouche, EBSTA Trainee

 I have obtained my diploma in Bioanalysis and Control in 2019 from the University of Salliège, Toulouse. It is during my undergraduate studies, when I have worked on the project that focussed on cachexia during breast cancer disease, that I was exposed to the research world for the first time. This experience has inspired me to continue in professional training in the field of biomedical research. To follow my dream, I have enrolled at renowned ESTBA school in Paris as a third year Bachelor student. I am excited to join the team of Dr.Panasyuk at INEM Institute as this training represents an excellent opportunity for me to work in the international environment with scientists of different levels and to learn diverse techniques. During my 9-month lab training, I aim to establish the portfolio of tools to study the class 3 PI3K signalling in plants! I am looking forward to convert my theoretical knowledge into practice by exchanging ideas and solving scientific problems. In future, I plan to continue my undergraduate studies to obtain MSc degree and I believe this training represents an essential step in my formation as future researcher.

Alioune Fall, Master student, Sorbonne University

I have obtained my degree in pharmacology at Clermont Ferrand University 1 in 2014. Next, I took some time off my studies and for four following years I have been engaged full time in a disability aid association. In 2018, I have integrated Paris-Est Créteil University to continue my undergraduate studies and from which I have obtained the M1 diploma with honours in 2019. It was during my M1 internship on genetic editing by CRISPR-CAS9 that I took the full measure of the importance and power of genetics and its tools to dissect complex biological problems. In 2019, I joined the laboratory of Ganna as part of my internship in my Master 2 genetic and epigenetics of the Sorbonne University. I am looking forward to contribute to a project that aims to understand the involvement of class 3 PI3K in human liver diseases.
