A little about me:
I am Aubs (they/them), and I’m finishing up my PhD in biological sciences at Columbia University. (Curriculum Vitae below.)
Studying life under the microscope has been my life-long love. As a child, I was investigating pond-water and bugs under a small kids’ microscope, and nowadays I’m privileged to investigate fibrosarcoma cancer cells under a confocal microscope. I care deeply about early access to hands-on science for under-served students and I co-founded and directed a free STEM outreach program for local Harlem families to invite them onto campus and run experiments with grad student researchers.
I also enjoy making art and hosting science-art salons to share and showcase scientific art pieces with friends and community.
My interests:
Investigating mechanisms of tumorigenesis and cancer persistence
Science communication and STEM outreach
Biological art and data visualization
Cancer cells (HT1080 human fibrosarcoma) undergoing ferroptotic death induced by small molecule compound RSL3 ((1S,3R)-RSL3). Transferrin Receptor 1 (TFRC) in red is a marker of ferroptosis, and accumulates in ferroptotic cells, also localizing that the plasma membrane.

Curriculum Vitae:
Postdoctoral biologist in Biological Sciences at Columbia University with comprehensive undergraduate biochemistry instruction and research mentorship experience. Doctoral research focused on high-throughput optical pooled CRISPR/Cas9 screening and spatial transcriptomics to investigate regulators of ferroptotic cell death in cancer. Strong interdisciplinary background spanning molecular biology, microscopy, and computational analysis. Committed to rigorous experimental design, inclusive curricula and course design, and translational research in the field of molecular biology.
