Detailed Notes from PhD Student Talk

Welcome and Introduction

  • Brief overview of the fall of 2021 at UConn amid COVID-19:
    • Students were returning to in-person classes with restrictions.
    • Anna, a standout student, participated in research during her undergrad.

Anna's Background

  • Anna is a second-year graduate student at UMass Chan in Worcester.
  • Undergraduate at UConn from 2019 to 2023, majoring in Medical Laboratory Sciences (MCE).
  • Conducted research in Alfredo Amales Bosa's lab focused on antimicrobial peptides (AMPs).
  • Transitioned to a PhD program, currently studying in the Shank lab, focusing on antibiotic resistance.

The Antibiotic Resistance Crisis

Two-Part Problem Overview
  1. Prevalence of Antibiotic-Resistant Bacteria:
    • Example: MRSA (Methicillin-resistant Staphylococcus aureus).
    • Antibiotic resistance is a natural occurrence exacerbated by human actions, especially in agriculture.
  2. Lack of Novel Antibiotics:
    • Sharp decline in antibiotic discovery post-1970s, termed the "discovery void."
    • Rediscovery of known antibiotics but not suitable for new medical applications.

Anna's Research

Undergraduate Research Focus
  • Studied antimicrobial peptides (AMPs) in the lab, synthesized from sea squirts.
  • Conducted experiments to assess the effectiveness of synthesized AMPs against E. coli using Minimum Inhibitory Concentration (MIC) assays.
  • Purification techniques included HPLC (High-Performance Liquid Chromatography) and mass spectrometry.
Graduate Research Initiatives
  • Current work involves microbial interactions to discover new antibiotics by culturing bacteria together.
  • Experiment design:
    • Compare monoculture vs. co-culture conditions.
    • Assess antibiotic production by examining zones of inhibition against pathogens (e.g., Staphylococcus aureus).
    • Analyzed gene expression via RNA sequencing to identify production signals and mechanisms.

Insights on Graduate School Experience

Choosing a Graduate Program:
  • Personal reflection on factors influencing Anna's choice:
    • Cohort size (50 students), opportunities for friendships, and extensive faculty (over 200).
    • Importance of lab rotations in diverse scientific fields.
    • Availability of support facilities for research (e.g., expertise in structural biology).
Advice for Prospective Students
  • Considerations when selecting a lab:
    • Funding situation.
    • Lab size and dynamics (5 vs. 30 students).
    • Opportunities for internships and industry exposure.
    • Hands-on vs. hands-off mentorship styles.
    • Importance of student connections in selecting a program and lab.

Reflections on Grad School Transition

  • Initial adjustment to graduate school is challenging.
  • Developed strategies for time management and self-motivation.
  • Stressed importance of peer support for maintaining mental health and work-life balance.

Importance of Microbial Communication

  • Relevance of microbial interactions in antibiotic discovery and therapeutic applications.
  • Potential parallels with dysbiosis and its implications for human health, particularly in relation to aging effects.

Conclusion

  • Anna's experience highlights the intricate balance of scientific research, educational choices, and personal growth during the journey through graduate studies.
  • Engagement with complex topics such as antibiotic resistance emphasizes the significance of innovative approaches in combating challenges in medicine.

Audience Engagement

  • Anna encourages questions from the audience regarding her research and experiences, promoting an open dialogue for further learning.
