Dr. Andrea Holgado is a Professor of Biological Sciences and serves as the Director of both Undergraduate Research and the McNair Scholar Program. In her role as a faculty member, she teaches courses in Cell Biology, Cancer Biology and Social Justice, and the Neurobiology of Mental Illness. Beyond her teaching responsibilities, Dr. Holgado mentors undergraduates in neuroscience research and actively promotes research initiatives throughout the campus.

Dr. Holgado joined the St. Edward's University faculty in August 2017. She earned her Bachelor’s in Biology Education, Bachelor’s in Biology, and Ph.D. in Biology from the National University of Cordoba, Argentina. Before becoming faculty at ¶¥¼¶¹ú²úÊÓƵ, she was a postdoctoral researcher at Northwestern University and the University of Illinois at Chicago. Her postdoctoral research focused on the molecular analysis of synapse formation and maintenance in hippocampal neurons in culture and in the model organism C. elegans. She began her career in teaching in 2005 as a non-tenure-track instructor in the biology department at Loyola University in Chicago and in 2008 joined the faculty in the Department of Biological Sciences at Southwestern Oklahoma State University (SWOSU), serving as an assistant and associate professor and department chair until 2017. Working at primarily undergraduate institutions (PUI), SWOSU and ¶¥¼¶¹ú²úÊÓƵ, she emphasizes research in science education using high-impact practices to train future members of the bioscience workforce, course-based undergraduate research experiences (CUREs) in laboratory courses, and mentoring undergraduates in co-curricular capstone experiences. Since 2008, she has mentored over 100 undergraduates, published research manuscripts, contributed to conference presentations, and served as the PI of OCAST, OK-INBRE, OK-EPSCoR, NSF-RUI, NSF Major Research Instrumentation, and NSF HSI grants. These efforts have resulted in her receipt of national and regional awards from the Institutional Network of Biomedical Research Excellence, the Oklahoma Foundation for Excellence, and the Oklahoma House of Representative Harold Wright.

 

Teacher & Scholar Philosophy

To describe my philosophy as an educator and scientist succinctly, I must quote Dr. Rosalyn Yallow, co-winner of the 1977 Nobel Prize in Physiology or Medicine. During the Nobel Prize banquet speech, Dr. Yalow said, "we bequeath to you, the next generation, our knowledge but also our problems. While we still live, let us join hands, hearts, and minds to work together for their solution so that your world will be better than ours and the world of your children even better".

Research

The primary aim of my research team is to uncover the mechanisms behind neuronal signaling and neuroplasticity. To achieve this, we focus on isolating and analyzing mutants in the soil nematode Caenorhabditis elegans (C. elegans) that disrupt these processes.

At present, we are investigating two critical processes related to neuronal signaling and neuroplasticity: (1) the development and maintenance of the neural network, and (2) cellular autophagy. While these processes are generally thought to be separate, our recent findings suggest a novel link. Specifically, the protein UNC-33 (the C. elegans counterpart of collapsin response mediator protein or CRMP), known for regulating axon length, appears to influence autophagy in a way that is not yet fully understood. Thus, our current research focuses on exploring the roles of UNC-33 and autophagy in neuronal development and survival.
