Emission Modes in Electrospray Thrusters Operating with High Conductivity Ionic Liquids
Aerospace, 2020 Electrospray thruster life and mission performance are strongly influenced by grid impingement, the extent of which can be correlated with emission modes that occur at steady-state extraction voltages, and thruster command transients.

A Parallelized Genetic Algorithm to Evaluate Asteroid Impact Missions Using Electric Propulsion
Aerospace, 2022 A streamlined genetic algorithm was developed and implemented on a GPU to evaluate low-thrust trajectories of spacecraft propelled by an ion thruster. It was then applied to examine the utility of a specific thruster for an asteroid impact mission.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Research on the life-limiting sputtering mechanism of 30 cm ion thruster
AIP Advances, 2022 “Pits-and-grooves” patterns on the downstream accelerator grid surface had a severe effect on the thruster life; however, the sputtering patterns on the decelerator grid upstream surface were also observed after the thruster worked for over 3000 h ...

Development of a Laser Micro-Thruster and On-Orbit Testing
Aerospace, 2023 Laser micro-thrust technology is a type of propulsion that uses a laser beam to ablate a propellant such as a metal or plastic. The ablated material is expelled out the back of the spacecraft, generating thrust.

Translating whole‐genome doubling into precision medicine in cancer
Molecular Oncology, EarlyView.Whole‐genome doubling creates a WGD‐positive tumor state characterized by persistent chromosomal instability, karyotypic diversification, and cellular stress. These same biological pressures drive aggressive tumor evolution while exposing therapeutic vulnerabilities, providing a rationale for WGD‐informed precision medicine. Whole‐genome doubling (WGD)
