Louise Showe received her bachelor’s degree in biology from Wilkes College (PA) and her master’s in developmental biology from Temple University. After gaining her Ph.D. in biology from the University of Pennsylvania, she moved to Europe to do her postdoctoral studies at the Biozentrum der Universitat, Basel, Switzerland. Dr. Showe joined The Wistar Institute in 1983 as an assistant professor.  She is presently a Professor in the Molecular and Cellular Oncogenesis program and the Scientific Director of the Wistar Bioinformatics and Genomics Shared Resources. She is also the associate director of the Wistar Center for Systems and Computational Biology. Showe was awarded one of the first ten National Cancer Institute Director’s Challenge grants to create new molecular criteria for the classification of cancers using microarrays and is presently funded by the Early Detection Research Network (EDRN) to continue this work.  The technology has been licensed by Oncocyte. 

Showe’s current research interests have focused on using genomics-based approaches and big data to better understand disease processes with an emphasis on the immune system and cancer. In addition, her laboratory has actively contributed to the development of genomics and bioinformatics at The Wistar Institute, focusing on the implementation of new methods for the generation and analysis of large and complex datasets.

Among her most recent work is the identification of biomarkers in the blood that indicate the presence of early-stage lung tumors in high risk populations of smokers and ex-smokers with the goal of developing non-invasive tests that will help to determine whether the large numbers of lung nodules detected by the growing numbers of LDCT scans being carried out each year. They have also used blood gene expression patterns to identify patterns that indicate which lung cancer patients are more likely to relapse after lung surgery, alerting clinicians to re-evaluate further treatment options. Additional studies have also investigated gene expression patterns in malignant and normal immune cells of CTCL patients in response to different treatments both in vivo and in vitro. The group’s diverse interests are shown by a long-term collaboration with the University of Fairbanks to study how hibernating black bears modify gene expression in various tissues during hibernation and her work with the University of Nottingham on multiple sclerosis.
