I’m an insect neurobiologist interested in understanding the powerful sense of smell insects use to locate food, find mates, and communicate with others. In particular, my research focuses on the chemical language of ants and the specific genes involved in detecting social cues. By characterizing the smell receptor genes of the Indian jumping ant, Harpegnathos saltator, we hope to understand the basic sensory requirements for successful ant societies. Our new research angles include exploring the evolution of chemical signaling in day-active fireflies and pheromone reception in longhorn beetles.
The Pask Lab combines approaches in molecular biology, genetics, electrophysiology, animal behavior, and chemical ecology to address these questions using both model and non-model insects.
Although space is limited, please contact me if you are interested in joining our lab group.
Courses Taught
BIOL 0145
Cell Biology and Genetics
Course Description
Cell Biology and Genetics
In this introduction to modern cellular, genetic, and molecular biology we will explore life science concepts with an emphasis on their integral nature and evolutionary relationships. Topics covered will include cell membrane structure and function, metabolism, cell motility and division, genome structure and replication, the regulation of gene expression and protein production, genotype to phenotype relationship, and basic principles of inheritance. Major concepts will be illustrated using a broad range of examples from plants, animals, and microorganisms. Current topics in biology will be integrated into the course as they arise. 3 hrs. lect./3 hrs. lab

Invertebrate Biology
Course Description
Invertebrate Biology
Insects are one of the most successful animal groups on Earth, accounting for roughly 75% of all animal species. This course will examine several aspects of organismal biology in insects and related arthropods, such as comparative anatomy, physiology, reproduction, development, sensory behavior, and evolution. Hands-on experiences with insects will occur in the field and the lab and will culminate in an independent research project. Special topics will include medical and veterinary entomology, insect pest management, and the effects of climate change on insect populations. Oral and written reports are required. (BIOL 0140) 3 hrs. lect./3 hrs. lab

Receptor Biology
Course Description
Receptor Biology
In this course we will focus on the wide range of membrane receptors and channels that are critical for cellular communication, neuronal connectivity, and sensory transduction. These complex proteins represent major targets in the pharmaceutical industry, and their study incorporates interdisciplinary techniques in structural biology, electrophysiology, synthetic chemistry, and pharmacology. After thoroughly engaging in the primary literature, we will emphasize discipline-specific writing and learn to summarize and communicate new findings to a wide range of expert and non-expert audiences. (BIOL 0145 or waiver) 3 hrs. lect./disc

Animal Physiology
Course Description
Animal Physiology
This course examines the body functions of animals and humans using general physiological principles and a comparative approach. Lectures will cover the function of each of the major physiological systems (nervous, endocrine, muscular, etc.) and will describe how animal physiology has been shaped by evolution to allow animals to survive in a wide range of environmental conditions. Lectures will focus mainly on physiological processes occurring at the molecular, cellular, and organismal levels. Occasional journal article discussions will provide case studies of current topics in animal physiology. Laboratory exercises, reports and oral presentations emphasize experimental design, analysis and independent study using various methodological approaches including electrophysiology, neurotransmitter manipulations, nutritional analysis, and exercise physiology. (BIOL 0140 and BIOL 0145 or NSCI 0251). 3 hrs. lect/disc., 3 hrs. lab.

Marvel Comics & Society
Course Description
Marvel Comics & Society
Comic books and graphic novels are a powerful storytelling medium that often connects to both contemporary cultural issues and human emotions. Marvel Comics has long used their pages to tackle issues of race, poverty, gender, identity, science, and justice, either indirectly or head-on. In this course we will analyze both the source material and scholarship related to Marvel comics, as well as learn to communicate our own analysis and stories in both written and oral forms. Note: This course will focus on the comics, not any of the Marvel Cinematic Universe films. Enrolled students must purchase a subscription to Marvel Unlimited (https://www.marvel.com/unlimited) for the duration of the term.
