  I earned my Ph.D. at University of Michigan, Ann Arbor, for work that examined how carbon enrichment redirects plants’ allocation of resources to growth, reproduction and defense.  In my postdoctoral work, I extended this line of inquiry below-ground to explore how soil microbial communities respond to plants’ carbon surplus when grown in carbon-enriched atmospheres. After coming to MSU, my research interests shifted toward questions that provide insights into how students develop conceptual understanding in biology.  I am especially interested in the barriers and benefits that accompany learning and reasoning with visual information.

Graduate Students

Joelyn de Lima

  I am a graduate student in the Long Lab, Department of Plant Biology, MSU. My research is focused on undergraduate biology education. I explore how context influences the way students reason about evolution, and the way they represent their knowledge and reasoning. Specifically, I study the variation in students’ responses to equivalent questions asked using different contexts, and the degree to which different modes of response influence the content and accuracy expressed. My research leverages analytic and statistical approaches used by population biologists and network scientists to test theories rooted in psychology and the learning sciences. In addition to my research, I am involved in various science communication and community building endeavours.

Bethany Gettings

  I am a third-year Ph.D. student and NRT-IMPACTS fellowship recipient in the Long Lab where I am interested in short- and long-term achievement differences exhibited by students in undergraduate biology courses taught through model-based instruction. I hope to use my research as evidence to inform instructional practices which are effective to the majority of students; ultimately, addressing the STEM achievement gap and increasing retention within STEM undergraduate programs.

Seth Hunt

  I’m a Ph.D. student in the Long Lab whose research joins traditional ecological research with discipline-based education research. My dissertation research looks at dissolved oxygen cycling in rivers and the different roles that various physical, chemical, and biological parameters play in it’s alteration. From an education perspective, I’m interested in systems thinking in ecological contexts with particular emphasis on how undergraduate biology students reason with nutrient cycling models.  I have a bachelor’s in biology with a secondary education option from Waynesburg University and a master’s in aquatic ecology from Murray State University.  Prior to joining the Long Lab I had previously worked at the University of Delaware as a preceptor where I helped teach integrated version of both introductory biology and introductory chemistry to freshman life science majors.

Research Associates


Jyothi Kumar

  I am the Program Coordinator for NSF Research Traineeship (NRT) - Integrated training Model in Plant And Compu-Tational Sciences (IMPACTS) at Michigan State University. NRT is designed to encourage the development and implementation of bold, new, and potentially transformative models for STEM graduate education training in high priority interdisciplinary research areas through a comprehensive traineeship model. The program aims to provide training for doctoral students at the interface of plant biology and computational sciences. As program coordinator, I am involved in understanding efficient ways to train graduate students in interdisciplinary research, estimate project impact on trainee outcomes, and develop a resource repository to support evaluation efforts across science education community. I have a Master’s degree in Biotechnology from Bangalore University, India and a PhD in Agronomy and Horticulture from the University of Nebraska Lincoln.

Undergraduate Researchers


Josh Marwede

  I am currently a freshman enrolled at Michigan State University’s College of Lyman Briggs pursuing a double major in Neuroscience and Psychology. After joining the Long Lab this past fall, I have been working with various forms of transcription involving undergraduate level biology and model-based data comprehension. Besides lab work, I am also apart of the American Medical Student Association and intramural basketball here at Michigan State. In the near future, I intend on furthering my education through medicine.

I am currently a senior studying within the College of Education, pursuing a degree in integrated biological sciences with an interdepartmental science minor. Following my graduation from MSU, I plan to work as an educator teaching science at the high-school or middle-school level within the state of Michigan. Besides work in the lab, I am involved with a few organizations such as a local fraternity and Camp Kesem at Michigan State University where I have volunteered as a camp counselor during previous summers.

  I am currently a junior enrolled at Michigan State University’s College of Agriculture and Natural Resources pursuing a major in Biomedical and Molecular Nutritional Sciences while following the pre-dental track. In the fall semester of 2020, I worked as an undergraduate learning assistant for Dr. Long, and was introduced to the research in the Long Lab. In the Long Lab, I will be working data obtained from undergraduate level biology and understanding model-based data comprehension. Outside of the lab, I enjoy cooking, travelling and shadowing dentists in hopes to further enhance my education in dentistry.

  I’m currently a junior enrolled in the College of Natural Science at Michigan State University majoring in Human Biology and minoring in Bioethics in hopes of entering the medical field by attending a P.A program after graduation in spring ‘22. I’m a recent addition to the research team as of spring ‘21 and had the pleasure of working with part of the lab team previously, for I was originally introduced to the research when working as an undergraduate learning assistant for Dr.Long alongside Hannah Ahmed this past fall. Aside from lab work, I volunteer for MSU’s chapter of global brigades with hopes to attend future medical brigades. I also enjoy vegan cooking and am obsessed with my cat Nina.
