Candidate: Marcella Birtele

I am writing to express my keen interest in joining the ISRB Board. As an accomplished researcher in the

field of regenerative biology with a strong background in electrophysiology and human neuronal modeling,

I believe I can contribute significantly to the advancement of the society's goals and objectives.

My passion lies in exploring regenerative medicine's potential as a tool to unravel the intricate mechanisms

underlying neurodevelopmental and neurodegenerative disorders. Specifically, I am deeply invested in

deciphering the molecular and functional intricacies of developing human neurons.

During my doctoral studies in the lab of Malin Parmar at Lund University, Sweden, I focused on delineating

the transcriptional and functional profiles of human fetal midbrain dopaminergic neurons, with a specific

emphasis on modeling Parkinson's Disease using human-derived in vitro systems. This work provided

valuable insights into disease mechanisms and potential therapeutic avenues.

In my postdoctoral research in Giorgia Quadrato’s Lab at the University of Southern California, Los

Angeles, I focused on understanding the role of autism spectrum disorder (ASD)-associated genes in human

brain development, particularly focusing on the gene SYNGAP1. Through a combination of experimental

approaches, including organoid cultures and electrophysiological recordings, I uncovered novel insights

into the non-synaptic functions of SYNGAP1 in cortical progenitors, shedding light on its role in

neurodevelopmental disorders. Moreover, my research has highlighted the importance of exploring the

intricate interplay between genetic factors and neuronal development across various cell types and

developmental stages, which is my current research focus as a postdoc.

Candidate: Kartik Soni

My name is Dr. Kartik Soni and I am Senior Researcher in the Laboratory of Drs. Albert E. Almada and Thomas Lozito at the University of Southern California (USC), where my research is focused on studying the super-healing properties of skeletal muscle using the green anole lizard.

I earned my Ph.D. from the Institute of Genomics and Integrative Biology, Delhi, where I studied RNA regulated gene expression in the context of development and disease using Drosophila and Zebrafish as model organisms, looking at the regulation of gene expression during early embryonic development and its epigenetic regulation by maternally inherited microRNAS.

I had a short postdoctoral stint at the Tajbakhsh lab at Institut Pasteur in Paris, France where I had the opportunity to study muscle stem cell biology during early development and induced injury models in mammals. My work primarily involved in vivo visualization of muscle stem cells during quiescence and activated states in various physiological states that included different kinds of injuries (freeze/mechanical, toxin, dystrophic mice, etc.), using intravital imaging, supported by other microscopic techniques.

Since 2022, I have been working on a project involving understanding why lizard skeletal muscle regenerates de novo in the lizard tail after amputation, whereas mice have more limited regenerative potential. As a researcher, I believe in the promise of regenerative biology to transform human health and disease. I am honored to apply to serve on the Board of the International Society of Regenerative Biology (ISBR). Being part of this distinguished group is a bonus but perhaps of greater significance to me is the opportunity to make a direct contribution to the direction of the field and its international scope.

This opportunity is just at the right juncture of my career to have a significant impact on my long-term career goals of pursuing research towards augmenting regeneration in humans. At this stage in my career, I am keen to interact and discuss with experts and opinion leaders in regenerative biology. I would like to learn about the latest developments, new ideas, and novel approaches that might be shaping the future of the field. I want to learn about current gaps, unanswered questions, and how we can address these. As an active member of your board, I would seek to use these opportunities to engage with fellow board members in a collaborative spirit to understand strategic issues and priorities, to identify opportunities for building multidisciplinary interactions, and to advocate for greater support and recognition for research in regenerative biology with funding agencies and policymakers throughout the world.

Being a member of the ISRB Board will provide an opportunity for me to practice and improve my leadership skills, expand my professional network, and raise my profile in the scientific community allowing me to make meaningful contributions as I actively participate in decision-making, organize conferences, and/or spearhead discussion sessions, workshops, talks and mentorship.

My desire to serve on the board of the International Society of Regenerative Biology (ISRB) stems from the passion that has long compelled me to follow my curiosity, to share in a unique scientific experience, and to collectively engage in research in pursuit of improving life for all. I sincerely hope to promote and improve the entire regenerative biology field by working together during my tenure on the ISRB board. Thank you for your consideration.

Candidate: Stephanie Tsai

My name is Stephanie Tsai and I’m currently a Helen Hay Whitney postdoctoral fellow in Dr. Jenna Galloway’s lab at Massachusetts General Hospital in Boston (USA). As a member of the regenerative biology community for the last 16 years, I’m thrilled to offer my candidacy to the members of the regeneration community to serve as a postdoctoral member of the board of the ISRB.

I have had a longstanding passion in regeneration research and am driven by my curiosity to understand why and how some organisms retain the remarkable capacity to regenerate tissues, appendages, and even whole bodies, while humans cannot. Prior to my PhD, I trained in multiple labs studying salamander limb regeneration since high school both within the USA and abroad (Randal Voss Lab, University of Kentucky; Kiyokazu Agata lab, Kyoto University; Clifford Tabin Lab, Harvard Medical School). For my graduate studies, I trained as a PhD student in Dr. Douglas Melton’s lab (Harvard University). My doctoral work broadly highlighted the importance of cytokine signaling in the initiation of limb regeneration. While I spent most of my career up to that point studying appendage regeneration, I decided to apply my regeneration expertise to the lesser studied world of connective tissues, specifically tendons, as a postdoctoral fellow and joined the Galloway lab where my research is focused on elucidating mechanisms driving tendon regeneration using both zebrafish and mice.

Over the course of my career, I have been lucky to have great mentors, especially when I was young, who not only trained me, but also encouraged and inspired me along the way. I am committed to paying it forward and would like to join the ISRB board to launch initiatives which provide career mentorship for trainees at all levels, present opportunities to grow the regeneration community and foster collaboration across different fields, as well as organize outreach opportunities to teach pre-undergraduate students and young kids about the wonders of regenerative biology.

I believe my past and present experiences will aid in carrying out these goals as a board member. In the past, I have successfully collaborated with other researchers in the limb regeneration field, mentored trainees (at the high school, undergraduate, and graduate levels), regularly participated in EMBO Regeneration meetings since 2016, and most recently co-authored a meeting report sharing findings from the last EMBO meeting (Barcelona, 2022) which was published in Development. In addition, I have served as a teaching assistant for an undergraduate development and regeneration course, guest lectured for an undergraduate regenerative and immunobiology course (Gettysburg College) and have also designed and taught a regeneration course as part of the Educational Studies outreach program at MIT. Outside of regenerative biology, I served as a member of the Tendon Section membership committee for the Orthopedic Research Society for 3 years, which is aimed at boosting diversity in membership (ex. geography, gender, race) for tendon researchers in the organization. I am also currently a mentor for the Science Club for Girls, a weekend program which aims to expose and inspire young girls (grades K-8) to enter various STEM fields.

In all, I believe my enthusiasm for regeneration and strong belief in the future of regenerative medicine will enable me to promote the growth of the ISRB and act in its best interests. For these reasons, I hope you will consider electing me as a board member and thank you for your consideration.

PhD representative

Candidate: Marylène Bonvin

My name is Marylène Bonvin and I am second year PhD student in the lab of Dr Charisios Tsiairis at the Friedrich Miescher Institute for Biomedical Research (FMI) in Basel. As a recent member of the ISRB, I am writing to express my interest in joining the board.

As someone who is energetic and proactive, I believe I can significantly contribute to the ISRB’s mission and objectives. Below you can find a brief overview of myself and why I am enthusiastic about this opportunity.

I hold a Master’s degree in Animal Molecular Life Sciences, with a specialization in Regeneration. During my biology studies, I have been fascinated by all developmental and regenerative processes. My academic journey in regenerative biology started with zebrafish in the lab of Prof. Anna Jazwinska in Fribourg (Switzerland). During this time, I had the opportunity to study the mechanisms behind the cell plasticity during zebrafish heart regeneration. To continue pursuing my interest towards regenerative biology, I joined the lab of Dr Charisios Tsiairis as a PhD student. I now study tissue patterning and regeneration of the cnidarian Hydra vulgaris. My main project focuses on a new aspect that has, so far, been poorly studied in this cnidarian. I am interested to find how metabolism influences cells self-organization in Hydra. Taking advantage of the simple axial organization of Hydra, I hope to better understand the impact of metabolic variability on shaping the cell identity.

Next to science, having grown up in the Swiss Alps, my love for the mountains remains an important part of my life. I enjoy spending my free time skiing or hiking. When I am not doing outdoors activities, I like going to theater plays and concerts with friends. Both in my hobbies and during my studies, I strive for progress and am eager to embrace change. For this reason, I have always enjoyed representing and actively supporting my community in different councils and associations. For instance, I have been an active member in my hometown ski club, and I have also served as a student representative on the Biology Department council at the University of Fribourg. Therefore, I will be very excited to represent PhD students within the regenerative biology field on the board and to have meaningful impact on the future direction of the society. Being part of the board as a second-year PhD student will also be an amazing opportunity for me personally, I believe it will bring me a valuable experience that will shape my professional growth.

I hope that I have shown you that I am genuinely excited about the prospect of contributing to the ISRB’s mission and serving its community. If given the opportunity to join the board, I am committed to help supporting current events and future projects. More specifically, I hope to contribute by promoting initiatives to expand the students’ community within regenerative biology. I am eager to bring my knowledge, enthusiasm, and vision to the table. And I am confident that, by working collaboratively with fellow members, we can elevate the IRSB to achieve greater excellence and make a profound impact.

Thank you for considering my application.

Kind regards,
