Trista Successfully Defended her Senior Honors Thesis!

Today, after much work, a lot of successes and many failed experiments, Trista successfully defended her Senior Honors Thesis in the Department of Chemistry and Biochemistry! In her time in lab, she has been awarded numerous scholarships, awards, and is a co-author on one manuscript that was recently published. The thesis defense is a testament to the hard work and dedication that Trista has shown over the last 2.5 years and the lab could not be happier for her and all her successes!

Successful Undergraduate Research and Scholarship Symposium for Trista and Mia!

Today, Trista and Mia had the opportunity to present their research at Duquesne’s Undergraduate Research and Scholarship Symposium (URSS) that is open all undergraduates conducting any form of research! Both of them spent most of the time talking with faculty, students, and guests to explain their work on DNA methylation genes and antibiotic development. Very proud of both of them!

Welcome CJ, Ella, and Nathan!

New year, new semester, new students. Today, the lab grew by adding three new students for the coming semester. Today we added CJ Booterbaugh (Jr, PSYC), Ella Jacoby (Fr, Biochem) and Nathan Philips (Soph, Biochem). We are excited to see what they can accomplish on existing and new projects in the lab!

FIRST HEISLER LAB PUBLICATION!

Today, our efforts, in collaboration with Dr. Thomas Montgomery (Duquesne) was published in ACS Organic & Inorganic Au (DOI: 10.1021/acsorginorgau.5c00098). The Montgomery group was interested in a novel synthetic pathway for producing 1,2,4-Triazolidines with multiple different substitutions.

Given the involvement of triazolidines in diverse bioactivities, we found that many of these compound possess antibacterial properties. Led undergraduate Trista Newman, this project has spurred new questions and avenues of research lead by PhD student Elias Griffin.

First Preprint goes live!

Today, the first preprint that the Heisler lab has had the honor contribute their expertise towards has gone live. A collaboration with Rita Mihailescu’s lab here at Duquesne shows the importance of DNA secondary structures in the regulation of the 5′ untranslated region (5’UTR) of a gene implicated in multiple sclerosis. Morgan (PhD student) and Zoe (NSF-REU and NIH-NURE student) contributed all of the molecular and cell biology in the paper!

Undergraduates Awarded Multiple Awards for ABASM!

Today, undergraduates Megan Lyons, Elizabeth Stahovich (Cascio Lab), Trista Newman, and Cate Chalovich all presented at the Allegheny Branch of the American Society for Microbiology Regional Conference in California, PA.

Elizabeth presented a poster on her summer research experience at at the University of Bern in Switzerland with a project that focused on neurolisteriosis, an infection of the central nervous system caused by the foodborne pathogen Listeria monocytogenes.

Megan presented a poster on her summer research experience at Penn State in Dr. Dudley’s on project that focused on Sequencing of the O-Antigen Region in E. coli using CRISPR Cleavage assays.

Cate presented, and was awarded with a Top Undergraduate Poster Presentation Award (and cash), a poster on her continued efforts to make knock out strains of Listeria to advance projects uncovering the interactions with host proteins.

Trista, whose abstract was selected for an oral presentation, was awarded with the Top Undergraduate Oral Presentation Award (and cash), for her efforts in identifying novel antibiotic scaffolds that target common foodborne-pathogens!

Congrats to everyone!

Dissertation Outline DEFENDED by Elias

As a part of the development of graduate students into scientist, each student is required to put together an initial draft of what they imagine their thesis might look like 3-4 years from now. Today, Elias successfully defended his plans for identifying potential scaffold to control the ever growing number of antibiotic-resistance pathogens as well as identifying the target and mechanism of an effector protein that Dr. Heisler has been interested in since 2017.

Bittersweet End to the Summer!

All of undergraduates presented posters today at the Annual Summer Undergraduate Research Symposium highlighting the work our URP, REU, and NURE students conducted over the summer! It was a great time for reflecting on the summer and to celebrate all of the student’s hard work!

Megan completes here summer at PSU

Megan got selected for a Food and Drug Administration funded summer research opportunity in the Food Science Department at Pennsylvania State University! Not only did she do a lot exciting research with Dr. Dudley’s group, she also have the opportunity to tour the FDA headquarters and see how they conduct their important research activities. 

Megan and Trista present at NCUR

Megan and Trista spent the day presenting their research at the National Council on Undergraduate Research (NCUR) symposium here in Pittsburgh. NCUR is dedicated to promoting undergraduate research, scholarship and creative activity in all fields of study by sponsoring an annual conference for students. Unlike meetings of academic professional organizations, this gathering of student scholars welcomes presenters from all institutions of higher learning and from all disciplines. Overall, this conference offers a unique environment for the celebration and promotion of undergraduate student achievement; provides models of exemplary research, scholarship, and creative activity; and offers student career readiness development.

Trista was awarded a Barry Goldwater Scholarship!

From Goldwater:

GOLDWATER SCHOLARSHIP AWARDS

As the result of an ongoing partnership with UWorld and the Department of Defense National Defense Education Programs (NDEP), Dr. John Yopp, Chair of the Board of Trustees of the Barry Goldwater Scholarship and Excellence in Education Foundation, announced that the Trustees of the Goldwater Board will be able to award 441 Goldwater scholarships to college students from across the United States for the 2025-2026 academic year. When these new awards are combined with the second year of support to 64 sophomores who received Goldwater scholarships in 2024, the total number will again be among the largest number of scholars ever supported in a single year. With the 2025 awards, the Goldwater Foundation has awarded 11,162 scholarships since 1989, the first year the scholarship was bestowed.

“The Department of Defense’s continued partnership with the Goldwater Foundation ensures we are supporting the development of scientific talent essential to maintaining our Nation’s competitive advantage,” said Dr. Jagadeesh Pamulapati, Deputy Assistant Secretary of Defense for Science and Technology Foundations, who oversees the NDEP program.

“We are proud to remain the Goldwater Foundation’s sole private sector partner for the second year and support undergraduates interested in pursuing medical research careers,” said Chandra S. Pemmasani, M.D., founder and CEO of UWorld. “It is inspiring to see how the foundation continues to motivate students to grow in their education and pursue their professional goals.

From an estimated pool of over 5,000 college sophomores and juniors, 1,350 science, engineering, and mathematics students were nominated by 445 academic institutions to compete for the 2025 Goldwater scholarships. Of the students who reported, 203 of the Scholars are men, 222 are women, and virtually all intend to obtain a Ph.D. as their highest degree objective. Fifty Scholars intend to pursue research careers in mathematics and computer science, 240 in the sciences, 88 in medicine, and 63 in engineering and materials research.
