I WANT TO SHARE MY SUCCESS STORY  

Claire RadtkeClaire Radtke - Biological Sciences, Ph.D.

Claire Radtke, a fifth-year doctoral student in the Department of Biological Sciences, recently won the fourth annual Graduate/Medical Student and Postdoc Communication Competition at the Wisconsin BioForward Annual Summit in October.

BioForward is Wisconsin’s collective voice for promoting biohealth initiatives through advocacy, talent development and partnerships that strengthen long-term impacts on the biohealth industry and research institutions. The BioForward competition challenged competitors to create a three-minute video explaining their research to non-scientific audiences in a simple, interesting, and relevant manner. The top five finalists were then required to present their research live at the BioForward summit on Tuesday, Oct. 29. Radtke’s video on her research of protein aggregates came in first place at the final competition.

Radtke works in the lab of Dr. Anita Manogaran, associate professor of biological sciences, researching how cells handle protein aggregates associated with fatal diseases such as Transthyretin amyloidosis — a disease which occurs when the tissues and cells in the body accumulate abnormal protein deposits.

Radtke has been fascinated with protein aggregates since learning about them in an undergraduate biochemistry class.

“The fact that proteins can go bad and cause some of these fatal diseases fascinated me, it struck me and just kind of stayed with me,” Radtke said. “When I was looking for graduate schools to apply to, I looked for a lab where I could do that type of research and could continue to investigate this topic. I saw that Dr. Manogaran is interested in this same phenomenon, so it motivated me to apply to Marquette.”

Manogaran is Radtke’s dissertation advisor and principal investigator on her research. Radtke sees Manogaran as a mentor who is supportive of her taking time away from her research to pursue outside interests such as the BioForward communication competition.

 


Kristen QuagliaKristen Quaglia - Biological Sciences

Kristen Quaglia, a fifth-year doctoral candidate in the Department of Biological Sciences, was recently awarded the prestigious Arthur J. Schmitt Fellowship. The Arthur J. Schmitt Fellowship identifies talented Marquette doctoral students and fosters their development as socially responsible leaders in the Marquette community and beyond.

One of the goals of the fellowship is to further students’ formation as leaders working for positive social change in the spirit of Marquette and Arthur J. Schmitt. This vision is accomplished through supporting their doctoral studies and promoting leadership development and opportunities.

Quaglia’s research focuses on mechanisms organisms use to cope with increasing temperatures, often due to the effects of climate change. Quaglia notes, “rising surface temperatures, even slightly above optimal living temperatures, can impact organisms by decreasing their fertility and their ability to reproduce.”

With an everchanging environment due to the impacts of climate change, Quaglia’s timely research aims to understand how organisms can reproduce despite these environmental changes by studying the mechanics of programmed cell death in the reproductive tissues of organisms.

Quaglia presented her research at WiSER (Wisconsin Science Education and Research Consortium) Conference hosted at the Medical College of Wisconsin on Saturday, Oct. 5. She will also present her work at the 25th International C. elegans Meeting in June 2025, hosted at the University of California Davis.

Quaglia credits the Arthur J. Fellowship with allowing her more dedicated time to focus on conducting her research and writing her dissertation, as well as time to engage in leadership opportunities with other student leaders across campus.  

When Quaglia is not researching and writing, she enjoys spending time outside around Milwaukee, playing in various softball and volleyball leagues, and curling up with a book and her cat, Greta.

Nicholas Langer - Chemistry, Ph.D.

Nicholas LangerNicholas Langer is a current doctoral student in the Department of Chemistry who was recently awarded the Richard W. Jobling Distinguished Research Assistantship. The award is made possible through a generous donation to Marquette University to encourage and support research activity by doctoral students in the fields of science and engineering.

Langer’s research focuses on two major classes of nanomaterials: quantum dots (QDs – the same material for which the 2023 Nobel Prize in Chemistry was awarded) and gold nanoparticles (Au NPs). Due to the small size of the nanomaterials (smaller than the wavelength of visible light), the materials have fascinating light absorbing properties that lead to their widespread use in LED displays, biomedical imaging, sensors, electronic devices, and much more. Nanomaterials are typically coated in other organic molecules to increase their stability and impart functionality. Langer’s research in the Kedem lab aims to understand the degree and nature of effect these molecular coatings have on the behavior of nanomaterials with respect to their catalytic activity as well as their ability to form ordered patterns on surfaces. He discovered a polymer coating for Au NPs that doubles their performance, showing that ligand design is a promising approach to the development of more efficient NP catalysts.

Langer has presented his work at the American Chemical Society’s fall 2022 and 2023 meetings, at various field-specific conferences, Marquette’s Celebration of Research and Forward Thinking symposia, as well as the 2024 Catalysis Club of Chicago’s Young Scientist Symposium.

When Langer isn’t researching, he enjoys exploring Milwaukee’s various districts and visiting Wisconsin’s state parks.


MMadison Suttonadison Sutton - Biological Sciences, Ph.D.

Madison Sutton is a current doctoral student in the Department of Biological Sciences who was recently awarded the distinguished Arthur J. Schmitt Fellowship. These awards go to individuals who are emerging leaders in their field and focus on furthering their development as leaders and mentors in their careers.

Sutton’s research focuses on songbird responses to climate change. She conducts her research at the H. J. Andrews Experimental Forest in Oregon and measures how climate and species interactions shape distributions and ultimately survival for birds. Every year, she mentors and leads students in the field to conduct their own research focusing on addressing our understanding of the natural world. She is also an active member in ecological societies and committees that focus on increasing representation and diversity in ecology.

Sutton is a first-generation graduate student from Stewartsville, New Jersey. She has been to 45 out of 50 states studying birds. When she is not out birding, she can be found reading, cycling or playing with her nephew, Rowan.


Nick Schneider

Nick Schneider - Biological Sciences Ph.D.

Nick Schneider, a 5th year doctoral student in the department of biological sciences was recently awarded the Rev. John P. Raynor, S.J. Fellowship for the 2023-2024 academic year. The fellowship is awarded to graduate students to “engage in advanced study and research to prepare themselves for professional lives of service to their community and country.”

Schneider’s research focuses on the protein pyruvate carboxylase, which is crucial for functional metabolism in humans. Schneider states, “Certain cancers love taking advantage of pyruvate carboxylase to rapidly grow and divide, making pyruvate carboxylase a promising drug target for cancer therapeutics. My project involves discovering drug-like inhibitors that target pyruvate carboxylase in cancer cells. Using verified pyruvate carboxylase inhibitors against cancer cells would cripple the cancer’s ability to depend on pyruvate carboxylase, reducing their ability to divide and metastasize.”

Schneider recently presented his work at the Midwest Enzyme Chemistry Conference and the Gordon Research Conference. He has plans to attend and present at both conferences again in 2024.


Carolin JoyCarolin Joy - Chemistry Ph.D.

Carolin Joy is a doctoral student in the department of Chemistry who has recently been awarded the prestigious Arthur J. Schmitt Fellowship. The Arthur J. Schmitt Scholarship Leadership Fellowship identifies talented Marquette doctoral students and fosters their development as socially responsible leaders in the Marquette community and beyond. One of the goals of the fellowship is to further students' formation as leaders working for positive social change in the spirit of Marquette University and Arthur J. Schmitt. This vision is accomplished through supporting their doctoral studies and promoting leadership development and opportunities.

Carolin’s research is centered on studying the phenomena of energy transfer that takes place during molecule-molecule collisions, primarily in the Interstellar medium (ISM). Carolin stated; “The study of rotational energy transfer holds significance in understanding the physical conditions of ISM that favor star formation, the evolution of galaxies, and the interpretation of astrophysical observations from telescopes.”  Carolin plans to present her research endeavors at the upcoming 54th Midwest Theoretical Chemistry Conference hosted by the University of Wisconsin, Madison.
