Simultaneous, Large Multi-Gene Delivery for Implementation of Fluorescent Reporter Spatial Multiplexing to Image Signaling Pathways
Published 2022“…However, the problem with spectral multiplexing is the large degree of spectral overlap from the broad shape of the reporter’s spectrum that leads to a blended signal masking which data belongs to which molecule. This dissertation describes the concept of spatial multiplexing to circumvent the limitations of spectral multiplexing, the challenges of designing a system to deliver multiple reporters simultaneously in culture, and the attempt to teach resilience in developing tools for understanding the nervous system in a 14-week course. …”

Investigations of Iron–Nitrogen Bonding at Synthetic Iron–Sulfur Clusters
Published 2022“…A combined spectroscopic and theoretical analysis of this redox series using variable-temperature 1H nuclear magnetic resonance spectroscopy reveals that oxidation events are primarily centered at the imido fragment, which takes on an iminyl ([NAr]•−) or triplet nitrene ([NAr]2•) configuration depending on the charge state of the molecule. Two-electron oxidation of [Fe4S4]+ anilido complexes results in formal aminyl radical reductive elimination, generating aniline, hydrazine, and/or azoarene as byproducts along with the corresponding [Fe4S4]2+ solvento adduct. …”

Similarity Metrics for Biological Data: Algorithmic developments for high-dimensional datasets
Published 2022“…Every cell in the sample can be individually profiled — the amount of each type of protein or metabolite or other molecule of interest can be counted. Understanding the molecular basis that determines the differentiation of cell fates is thus the holy grail promised by these data. …”

Engineering plant-microbe communication for synthetic symbioses
Published 2023“…To the best of our knowledge, this is the first demonstration of engineered microbe-to-plant communication using a small molecule. We were also able to place the biosynthesis of pC-HSL under the control of various sensors and use an engineered consortium to perform logical operations on multiple environmental inputs. …”
