The cell’s ability to grow, develop, and respond to a changing environment is dependent upon proper movement of these cargoes. Membrane trafficking abnormalities can be observed in diseases like cancer and neurodegenerative disorders, but we have not yet determined the therapeutic benefits of correcting them. An important obstacle is that only some of these cellular transport pathways are well studied, while others are poorly understood.   Our research investigates the membrane trafficking events that enable the cell to adapt to conditions of stress and starvation, particularly examining the cellular compartments and proteins responsible for transporting critical lipid membranes and membrane-associated proteins within the cell. We use baker’s yeast to investigate new pathways and to identify the specific cargo molecules, like proteins, that move along them. This involves genetic manipulation of yeast and observation of fluorescent cargo proteins trafficking throughout the cell.   Publications: http://www.ncbi.nlm.nih.gov/pubmed/?term=segarra+va [post_title] => Veronica Segarra [post_excerpt] => [post_status] => publish [comment_status] => closed [ping_status] => closed [post_password] => [post_name] => veronica-segarra [to_ping] => [pinged] => [post_modified] => 2021-08-31 08:51:25 [post_modified_gmt] => 2021-08-31 12:51:25 [post_content_filtered] => [post_parent] => 0 [guid] => https://www.highpoint.edu/?p=98217 [menu_order] => 0 [post_type] => faculty-staff [post_mime_type] => [comment_count] => 0 [filter] => raw ) [1] => WP_Post Object ( [ID] => 94350 [post_author] => 62 [post_date] => 2021-05-25 15:22:49 [post_date_gmt] => 2021-05-25 19:22:49 [post_content] => My research addresses mammalian anatomy, diversity, and evolution through the Cenozoic era (66 Mya – present). I am interested in understanding the relationship between morphological variation and functional and ecological factors, what evolutionary processes are acting on a given clade, and how changes in diversity and evolutionary rates are related to ecology and adaptation.

His research and teaching focus on the evolutionary history of life on earth. As a paleoecologist, he investigates the effects of environmental change on communities of mammals at various times throughout the past, from the last Ice Age to 60 million years ago. His research utilizes large paleontological databases such as NEOTOMA and the Paleobiology Database (PBDB). He has received National Science Foundation funding to use the PBDB to provide authentic research experiences in undergraduate classes. Dr. George is originally from Stroudsburg, PA and graduated from Franklin & Marshall College, the University of Florida, and received his PhD in Geological Sciences from The University of Texas at Austin.   ResearchGate Profile: https://www.researchgate.net/profile/Christian_George2   Publications:   George, C.

My previous research was on the post-fire invasion of Paulownia tomentosa in xeric and sub-xeric Appalachian vegetation communities. This work developed a model of the fire and environmental conditions which enable the initial invasion pattern, and which enable the species to persist over subsequent years.   My most resent work has been a pyrodendrochronological study of Pilot Mountain State Park. This study used fire scars to document the fire history for the park area from 1849 to 2017 and has used by park managers as they determine how to incorporate prescribed fire to maintain and restore native fire dependent species. I am currently beginning a pilot study to develop a similar history for Hanging Rock State Park.   I have also conducted research with students on coal ash impacts on riverbank microbial communities’ structure and function. This work documented the impacts of the 2014 Dan River coal ash spill 1- and 3-years post-spill.
