Harry Tran, PhD

I completed my education in France, where I investigated the well-known "Jennifer Aniston neurons" and the face-selectivity properties of neurons. In January 2020, I joined the Biomedical Engineering Department as a postdoctoral researcher and am currently transitioning to a research scientist role. My research primarily focuses on understanding the behavioral and physiological effects of non-invasive brain stimulation on neural activity, with the aim of developing new methods to help individuals suffering from brain disorders. My work spans computational simulations, human research, and animal studies.

I have served as the treasurer of the PDA for nearly two years, while also contributing as a member of both the Policy & Advocacy and Social Committees. Throughout this time, I have managed budgets, overseen expenditures, and worked diligently to enhance the working conditions for postdoctoral researchers, striving to foster a more supportive and productive environment.

Serving as treasurer of any association is a pivotal responsibility, and I have collaborated closely with fellow PDA leaders to ensure the financial stability of the organization throughout multiple fiscal years. This role has provided invaluable experience in team dynamics, communication, and leadership, significantly enhancing my ability to steer group initiatives effectively. In addition to honing my financial management skills, it has also given me the opportunity to connect with researchers from diverse departments and broaden my professional network.

Spotlight for November, 2024

Courtney Matson, PhD

My name is Courtney Matson and I am a Cancer Research Institute Weismann Fellow in Dr. David Masopust’s lab at the Center for Immunology. I completed my Bachelor's at James Madison University in 2015 and my PhD in July of 2020 at the University of Maryland Baltimore School of Medicine where I studied the internal circuitry of T cell signaling. My postdoctoral research focuses on tissue resident memory T cells that live in all your body’s tissues and provide a first line of defense against pathogens and cancer. Unfortunately, these T cells also contribute to autoimmune diseases, and I am hoping to understand how these cells play both protective and pathogenic roles to develop new strategies for immunotherapies. I am hoping to move into an academic faculty position to continue to pursue these questions in a variety of autoimmune conditions to dissect how our immune system plays a central role in the initiation, maintenance, and resolution of autoimmunity. 


Outside of the lab, I love to explore Minnesota, read cliche rom coms, crochet and knit, and spend time with my cats, Wallace and Gromit. As a first-generation scholar, I love to teach, mentor, and provide outreach to support interest and accessibility to pursue STEM higher education. I am also very passionate about improving the postdoctoral experience. I worked with the Postdoctoral Association as well as the Medical School Postdoctoral Council the past two years to develop and implement new policies for postdocs. I am looking forward to seeing some of these projects come to fruition here at UMN and continue these endeavors as I lead my own lab in the future!

Melissa Simone, PhD

I am an eating disorders T32 postdoctoral research fellow in the Department of Psychiatry & Behavioral Sciences and the Division of Epidemiology & Community Health. I obtained my Ph.D. in quantitative psychology and sociobehavioral epidemiology in 2018 from Utah State University. Shortly after completing my Ph.D., I moved to Minnesota to pursue additional training in multidisciplinary eating disorder research.

My research interests are centered on understanding the socio-ecological risk and resilience factors that contribute to disparities in mental health and well-being in queer and trans young people and investigating possible avenues by which such disparities might be rectified. My research considers mechanisms across multiple domains and levels of influence (e.g., interpersonal, community, structural) through the application of advanced statistical methods that illustrate the complexity of factors contributing to health disparities. As an applied methodologist, I aim to develop more nuanced psychometric tools in populations that have been historically excluded from psychometric research. Psychometric studies are crucial in the health disparities research as many of the commonly used measures were developed for and validated in largely homogenous groups (e.g., White, well-educated), and thus may underestimate or fail to detect pertinent factors as experienced by young people with socially minoritized identities. Thus, my quantitative research works to develop and validate psychometric tools that accurately reflect the experience of diverse populations.

As a first -eneration scholar, I am passionate about teaching and mentoring students who have been historically excluded from academic spaces and I am deeply committed to increasing access to research, mentorship, and sponsorship to trainees. When I’m not working, I enjoy spending time with my dog and partner, taking care of my houseplants, and outdoor activities like mountain biking, hiking, and kayaking.

Benjamin Tansi, PhD

PDA Representative to the Academic Freedom and Tenure Committee.


I am a post-doctoral associate working under Prof. Steve Severtson in bioproducts and biosystems engineering.  Prior to this, I earned my B.S. degree in Chemistry at Juniata College in Huntingdon, Pennsylvania before pursuing my Ph.D. at the Pennsylvania State University.  While at Penn State, I explored artificial motility, especially by the use of plasmonic nanoparticles and various photochemistry.  During this time, I had the opportunity to present my research domestically and abroad, having spoken at multiple ACS Colloids meetings as well as at a Gordon Research Conference in Les Diablarets, Switzerland.  

Since coming to the U, I have taken on another colloids challenge by exploring the use of cellulose nanocrystals in inexpensive, green adhesives. I have also become involved with the UMN post-doctoral association within which I am eager to support continued efforts towards advocacy and professional development. To this end, I am honored to now serve as the representative to the Academic Freedom and Tenure Committee.

Outside of the lab, I take every opportunity to play soccer, hockey, and music. It’s been a tough year for these, but Minnesota has turned me into an avid cross-country skier in the meantime.

Catalina Picasso Risso, PhD, MS, DVM

I am a veterinary epidemiologist working as a postdoctoral associate at the Center for Animal Health and Food Safety, College of Veterinary Medicine, UofM. Additionally, I am an adjunct professor at the University of Uruguay teaching advanced statistics and epidemiology for veterinary students. I obtained my veterinary degree in 2009 in Uruguay and after working for 5 years as an official veterinarian at the Ministry of Livestock, Agriculture, and Fisheries in my home country, I moved to MN to pursue my MS (2016) and PhD (2019) on the epidemiology of bovine tuberculosis.

My research interest is in the application of quantitative epidemiological methods with a participatory approach, to study infectious diseases and inform decisions that can alleviate their impact on farming, community development, and public health. I work globally in low and middle-income countries (LMIC), and locally focusing on endemic infectious diseases. I am currently working on the use of diagnostic tests for African swine fever in Vietnam, and in the understanding of the role of vehicle movements on disease spread in the swine industry within the US. As well as a fellow for the UofM Center of Global Health and Social Responsibility, I dedicate part of my time working on reviewing the research conducted on zoonotic tuberculosis in LMIC to identify gaps in knowledge of the status, transmission, and control of the disease in animals and humans. I am also conducting a large scope project on the assessment of control strategies for bovine Tuberculosis in Uruguay.

I am passionate about research and teaching, but while not working, I enjoy spending time with my family and friends, and outdoor activities such as running, hiking, snowshoeing, and skiing.

Dennis Makau,PhD

I am a postdoctoral associate at the Department of Veterinary Population Medicine, University of Minnesota, Twin Cities. My current research employs statistical & phylodynamic modelling and machine learning techniques to understand the epidemiology of porcine respiratory and reproductive syndrome virus (PRRSV), anti-microbial resistance (AMR) in animal populations, and contact networks/animal movements. I graduated with a veterinary degree from the University of Nairobi, Kenya in 2012 and a Master of Science in Veterinary Epidemiology and Economics from the same university in 2014 under a scholarship funded by the University of Nairobi and International Livestock Research Institute (ILRI). My research at this level focused on the epidemiology of parasitic infections in companion animals (helminths) and cattle (Eimeria). In 2015, I moved to Canada to pursue my PhD supported by the Queen Elizabeth II Diamond scholarship, where I graduated with a PhD in Epidemiology from the University of Prince Edward Island (UPEI) in 2019. I was also the recipient of the 2019 Governor General's Gold Academic Medal (Canada) and the Faculty of Graduate Studies Award of Distinction, national and university-based awards respectively, for academic excellence at the graduate level. My PhD research focused on small-holder dairy management for sustainable livelihoods in rural communities in Kenya. 

My research interest is using molecular tools, applied-epidemiology and One-Health concepts, to enhance decision making in addressing threats and challenges in communities. My research outputs support resilient and sustainable livelihoods through the implementation of data-driven decisions for strategic interventions and policy development.

Shannon Negaard-Paper, PhD

Secretary of the UMN Post Doctoral Association 

Shannon Negaard-Paper was raised in North Dakota and earned a B.S. in both mathematics and electrical engineering from the University of North Dakota (UND). She moved to Minneapolis in 2010, when she was accepted to the University of Minnesota’s Ph.D. program in mathematics. Her dissertation focused on dynamical systems which allow for non-uniqueness in forward and/or backward time – a generalization of flows, semi-flows, and maps. This allows for studying systems that lack certain smoothness properties. Such systems arise naturally, including in climate mathematics. In fact, many problems from her research group – the Mathematics of Climate Research Network – provided motivation for this research.

While a student, Shannon also relished the opportunity to teach. She was an undergraduate teaching assistant at UND. As a graduate student, she earned an Outstanding Teaching Assistant award and was appointed lecturer for 8 of the 21 courses she taught, one of which was as course supervisor. She learned a lot about leading and appreciating the decisions other leaders have made, as well as being accountable to those who depend on one’s preparation.

Shortly after defending, Shannon accepted an industry postdoctoral position at the Institute for Mathematics and its Applications (IMA). The IMA partners academic rigor and insight with problems from industry and government. In that position, she has worked on theory-level research in graphical neural networks and a myriad of data science projects with Cargill, Inc. Those include projects in finance, root cause analysis for factory safety, and computer vision solutions.

When not working on mathematics or debugging code, Shannon enjoys too many hobbies. Her longest-running loves have been dance, cycling, knitting, skiing, and backpacking. She has helped run a local volunteer-based science-fiction convention for over 6 years (where she also cosplays), and she proudly serves as an Assistant Head Election Judge for the city of Minneapolis. Shannon also plays board games, draws, and enjoys her circus-based fitness and performance community.

Guru Venkatesan, PhD

Vice President

I’m a postdoc in Mechanical Engineering. I work on drug delivery systems and 3D bioprinting. I joined PDA to meet new people and be involved in activities concerning postdocs. I helped organize a few events, update our logo, and implemented a double-blinded judging approach for PDA’s Career Development Awards to remove biases. I represent postdocs in the Senate Committee for Faculty (and Postdoctoral) Affairs. My mission is to advocate for University programs and policies that more effectively support postdocs with academic and non-academic career goals. 

Got a fantastic new idea to improve the way we do things at PDA? Come join our team and make it happen!

Sam Nemanich, PhD, MSCI

PDA Steering Committee Member

I am a post-doctoral associate in the Department of Rehabilitation Medicine and Division of Physical Therapy. My work focuses on children and infants who have experienced brain injuries such as a stroke, and developing novel and effective rehabilitation interventions to improve their movement function.

I was fortunate to be a recipient of the PDA career development award, and have been involved with the PDA steering committee since last fall. I will also be post-doctoral representative working with the Graduate School-wide writing initiative advisory committee.  My goal is to contribute to the development of the post-docs at UMN. I regret not getting involved with the PDA sooner as there are many great opportunities to advocate and connect with other members. 

My spouse Sarah is also a post-doc at UMN, and we have two children: Theodore, 3 and Lucille, 8 months. Most of our time is spent with them, and when it’s warm, we love biking around Minneapolis and enjoying its wonderful park system.

Katie Block, PhD

PDA Secretary

PDA Communications and Outreach

Hello! I am a postdoctoral fellow in the Center for Immunology and study the effects of infectious history on the immune response to allergens. I joined the PDA and took over “Communications and Outreach” in 2016 and was elected Secretary this academic year. You probably met me at the PDA table if you went to New Employee Orientation, and I send you these newsletters twice a month. I also re-made our website this year (have you checked out pda.umn.edu yet?). I got involved with the Postdoc Association because there are a lot of resources available to postdocs, but we don’t always know what’s out there for us. It’s my goal to help postdocs find the resources they need, and help create them when they don’t yet exist (like the NIH K Award workshop I co-organized this winter). When I’m not in the lab and there aren’t three feet of snow on the ground, you can find me kayaking on one of Minneapolis’ lakes.
