The clinical lab is rewarding work for me and I will pass the board as a **Medical Laboratory Technician**, MLT(ASCP), with expectations to further distinguish myself in the field as a **Certified Pharmacy Technician** (CPhT). > #### My mission is to deploy Cryo-Electron Microscopy (CryoEM) to examine the shape, purpose, and how a cell's tools, called ==proteins==, work. > ##### Leveraging this data—while existentially exciting—continues to address disease at the molecular level and informs our understanding of threats to public health.^[Jeyaraj G, Rajendran AK, Sathishkumar KK, Almutairi B, Vadivelu A, Chokkakula S, Xie W. High-resolution protein modeling through Cryo-EM and AI: current trends and future perspectives–a review. Frontiers in Molecular Biosciences. 2025 Oct 23;12:1688455. doi: 10.3389/fmolb.2025.1688455] To advance in my studies I'm locating shadowing opportunities in transmission electron microscopy (TEM) in central Ohio for sufficient scoping practice to one day specialize in **CryoEM**, a type of TEM. Instead of conventional microscopy using light to see things, I am excited to deploy CryoEM to explore the invisible features of health. This is an exceptional workflow by reconstructing the contents of cells, effectively taking a snapshot and [digitizing them as they are](https://youtu.be/vLo7oqfRa74?si=5SzTqsVFksqfHPrr) in real time: ![[mn-example-starfile.mp4]] --- Between school and work you can find me enjoying life with my husband and mini aussie traveling, talks around a fire with friends, and finding new enriching experiences as part of lifelong learning.  **From left: my husband, Paul; our mini aussie, Dodger; and I.** # Latest Projects ### Studying the PTCE I'm happy to share [what to study to obtain a CPhT](Prepare%20for%20the%20PTCE.md) in 2026 created with qualified friends of mine who are are state licensed or nationally recognized (RPhT/CPhT). ### Science Visualization I make sense of researcher data by visualizing key parts of biomolecules that plays nicely with our eyes. By obtaining data from the RCSB Protein Data Bank^[Berman HM, Burley SK. Protein Data Bank (PDB): Fifty-three years young and having a transformative impact on science and society. Quarterly reviews of biophysics. 2025 Jan;58:e9. doi: 10.1017/S0033583525000034], I identify important sections that are relevant for clinical, educational, and translational applications. ### Technical Writing I'm filling in my knowledge gaps by writing a manuscript over [Basic Protein Science](Basic%20Protein%20Science.md). This self-study serves as a review for my future studies as a Technologist in Molecular Biology, or MB(ASCP). # Contact - [ORCID](https://orcid.org/0009-0000-3548-3303) [Zotero](https://www.zotero.org/lemasterdj) [LinkedIn](https://linkedin.com/in/lemasterdj) [Instagram](https://instagram.com/lemasterdj) - [email protected] - [(614) 604-2565](tel:6146042565)
