I am passionate about basic research and technical challenges. I love applying physics to new biological systems and performing advanced and highly technical experiments. I particularly enjoy working on new systems and implementing new techniques and technologies in understudied systems. I am also passionate about entrepreneurship and building open source production chains that make technology and repairability more open and available to everyone.
During my research, I have worked on a large variety of microscopes and microscopy techniques in challenging systems. For my core research project, I worked on the non-model organism Spirostomum. This organism is capable of incredibly rapid contraction, presenting many difficulties that needed to be overcome for imaging. I designed and implemented innovative techniques for mounting, fixation, and imaging of Spirostomum. In addition to multiple light imaging modalities I have also performed electron and AFM imaging on the organism and related proteins.
I am passionate about working on the technical side of science, including using new systems and techniques as well as developing novel methods. I am proficient in a significant number of microscopy and biological techniques including optical systems, microscopy maintenance, data analysis, image processing, biophysics, working as a microscope manager, and electronics design. I have a diverse set of skills that I believe can contribute to groundbreaking science and work with novel biophysics problems.
My expertise also extends to more advanced techniques such as immuno-TEM, microinjection, and working with custom optical setups. I have also worked as the superuser of an AFM for 3 years, where I have trained new users to run the equipment and helped run student labs. These experiences have honed my technical abilities as well as my teaching and communication skills, which I am eager to bring to your team.
I have also founded the company Koinslot, which aims to bring technology into underserved communities to get students excited about programming using gaming. This project aims to provide a fully open source hand held device that is easy to program and modify for teaching purposes. I personally designed the device, case, and hardware-level code backbone. This has combined many of my interests from electronics, programming, 3D printing and teaching. I am quite proud of the resulting company which is now mostly self-sufficient and capable of running under the guidance of my brother and co-founder.
I will be graduating with my PhD in physics in the summer and I am actively seeking a position outside of the US to advance my career. I am interested in learning new languages and broadening my cultural knowledge.

PhD Candidate/Biophysics Researcher - NCSU, Elting lab
I worked on graduate research projects in Dr. Elting’s Lab as a research assistant in pursuit of my PhD. The lab focuses on cellular biophysics using a variety of methods. My research focuses on investigating the cytoskeleton of Spirostomum ambiguum, often called “the fastest cell” due to its ability to contract its giant single celled body in the blink of an eye. We found that its contraction is due to the unique filaments known as the myoneme that allow it to contract without using traditional contractile machinery. We found that the myoneme mesh is calcium activated and just through shortening of the filaments is able to recapitulate the organismal shape change. We began to investigate the molecular basis for myonemeal force generation and speculate on it being generate by a modulated entropic spring mechanism.. In addition to this project, I also worked on building and improving the design of magnetic tweezers as part of the synthetic cytoskeletons project.
Magnetic tweezing: Separate approaches were used to build magnetic tweezers, the first being a large pointed solenoid fabricated from mu-metal, a high magnetic permeability metal idea for the project. The second was a novel approach using a yoke to wrap the magnetic field back on itself that accomplished similarly high fields using less material and allowing for 2D spatial control of the field. Quantification of the forces that these devices were able to apply to magnetic particles in different solutions was done with an undergraduate student in the lab. Future applications of the tweezers include using them to emulate cytoskeletal transport, structure and force generation
Immuno-TEM imaging of Spirostomum Ambiguum: I performed the advanced imaging technique, Immuno-TEM on the Spirostomum myoneme. This technique labeled centrin on the myoneme both confirming the presence of centrin in contracted and elongated cells and showing the structure of centrin binding filaments in the myoneme. I further analyzed the structures of the uncontracted myoneme using ai-computer vision and graph theory analysis. These data require advanced technique development including novel fixation methods, microtomy, labeling methods, and TEM scope usage.
Confocal fluorescence imaging of Spirostomum Ambiguum: Spirostomum presents many unique challenges that need to be overcome for imaging. For one, its ability to contract presents issues with live imaging making it necessary to use high speed imaging to capture it. Additionally, Spirostomum is sensitive to many chemicals, it even finds use as a model organism for the detection of contaminants in water. This sensitivity makes fixation for IF or SEM difficult and some unique methods needed to be used to use these imaging modalities. I have also applied image analysis techniques using Imagej and used biophysical modeling to understand force generation of the Spirostomum cytoskeleton.
Multiscale computational modeling of Spirostomum Ambiguum myoneme and related proteins: I performed MDS simulations to analyse the effects of calcium binding to the myoneme. Some preliminary results showed that the myoneme changes persistence length as measured by correlation function of the angles between residues of Sfi1. To model the effects of filament contraction across the whole organism, I worked with Carlos Floyd to develop models of the whole Spirostomum informed by Fluorescence microscopy. These models used energy minimization with the myoneme modeled as springs and were able to recapitulate the shape change of Spirostomum contraction using a minimal model.
Worked in Dr. Dougherty’s Group in condensed matter. Experiments with growing monolayer transistors using vacuum deposition. Experience with AFM, Glovebox, spin coaters, vacuum chambers, and Lasers
Work consisted of creating organic semiconductor devices using the novel material C8-BTBT. We investigated surface effects on field effect transistors that were grown with C8-BTBT in monolayers. We found that initial layers of c8btbt exhibited a change in crystal structure when grown on a surface vs bulk. The surface grown C8-BTBT showed defects that prevented large devices from functioning, however the first few layers of a field effect transistor have been shown to contribute most to charge carrier mobility. Additionally we found defects created by the deposition of gold contacts on top of C8-BTBT monolayers.

Abstract
Spirostomum is a unicellular ciliate capable of contracting to a quarter of its body length in less than five milliseconds. When measured as fractional shortening, this is an order of magnitude faster than motion powered by actomyosin. Myonemes, which are protein networks found near the cortex of many protists, are believed to power Spirostomum contraction. Fast contraction, slow elongation, and calcium-triggering are hallmarks of myoneme-based motion. The biochemical basis of this motion and the molecular mechanism that supports such fast speeds are not well understood. Previous work suggests that myoneme structures in some protists are rich in centrin and Sfi1 homologs, two proteins that may underlie contraction. Centrin undergoes a significant conformational change in the presence of calcium, allowing it to bind to other centrin molecules. To understand Spirostomum contraction, we measure changes in cortical structures and model contraction of the whole cell and of the underlying protein complexes. We provide evidence that centrin/Sfi1 structures are responsible for contraction, which we propose is powered by a modulated entropic spring. Using this model, we recapitulate organismal-scale contraction in mesh simulation experiments and demonstrate the importance of structural organization of myoneme in a fishnet-like structure. These results provide a cohesive, multiscale model for the contraction of Spirostomum. Deeper understanding of how single cells can execute extreme shape changes holds potential for advancing cell biophysics, synthetically engineering contractile machinery, and cellular-inspired engineering designs.
Imaging of archaea with SEM and ExM
For this project I worked with Dyke Mullins lab to perform SEM and ExM imaging of a number of understudied organisms. I performed one of the first ExM experiments on archaea at the time. We also produced some of the first SEM images published on some of these organisms.

Coordinated movement of snowflake yeast
For this project I worked with Will Ratcliff’s lab to investigate the behavior of genetically modified yeast that was selected for clumping and multicellular like growth. We found that the yeast was able to under go directed movement to produce organism-like shape change despite not being selected for directly. This has implications for the transition of single celled organisms to multicellular. We found that the development of coordinated movement of cells and organization could emerge just from entanglement of cells without being selected for directly, potentially allowing for what has been thought of as a huge hurdle in the development of multicellular life to be overcome.
Condensate separation of rRNA in the nucleus
For this project I worked with Cliff Brangwynne’s lab to microinject labeled rRNA sequence as well as SARS-COVID RNA to investigate the condensate dynamics of the nucleolus. This project showed that sequences were able to separate into different parts of the nucleolus, showing the importance of sequence dependent condensation for the organization of the nucleolus.

[a]I've left a bunch of suggestions based on what I tend to see and look for in CVs from postdoc applicants, and also trying to make sure that some things that are really fantastic about your experience don't get lost. But there are two things about you that I think of as real strengths that I don't feel like are yet coming through as clearly as they could:
1. your ability to pick up and learn new methods, especially ones that are technically challenging, on your own or by finding independent mentoring outside the lab
2. your experience mentoring and working with undergrads (e.g., DJ, Noah, and others, but those are the first two that come to mind)
The first one I think can probably go in the researcher position description describing your work in my lab.
For the second, I think I'd suggest adding a section maybe titled 'leadership roles' or 'leadership and mentoring', something like that. That section could also include your role as the super user for the EARL AFM (and an explanation of what that means - not sure people will know offhand that it means you provided training to others and maintenance for the equipment, rather than just used it a lot). I know this info is in the 'skills' section, but I think it's kinda buried down there.
[b]Actually, another thing not on here is Senior Design. I think with the right title that could also go in the new section I'm suggesting. Or it could go under the education section with your undergrad degree.
