Hands-on diagnostic methodology, automated instrumentation, and discrepancy resolution across core clinical laboratory disciplines:

• Hematology & Hemostasis: Operated HORIBA ABX Micros CBC and automated coagulation analyzers; conducted manual 100-cell differentials, morphologic evaluations for acute leukemias, reticulocyte counts, and ESR.
• Immunohematology / Blood Bank: Executed tube, solid phase (Werfen SPRCA/Capture), and Ortho MTS Anti-IgG gel card methods for ABO/Rh typing, discrepancy resolution, antibody identification panels, crossmatching, and fetal screens.
• Clinical Chemistry: Operated ACE Axcel (ISE module) and Sebia SPEP systems; evaluated Westgard multi-rules and resolved out-of-control runs.
• Diagnostic Microbiology & Mycology: Plated cultures, performed Gram/AFB stains, automated VITEK ID/AST, Kirby-Bauer susceptibility, and identified anaerobic bacteria, fungi, and parasites.
• Urinalysis & Body Fluids: Conducted macroscopic and automated urinalysis (Siemens Clinitek), microscopic sediment review, and cytological evaluation of synovial, pleural, and CSF specimens.

Hospital Clinical Practicums (Audie L. Murphy Memorial Veterans' Hospital) commencing November 2026 across Clinical Chemistry, Urinalysis, Hematology, Immunohematology, Microbiology, and Flow Cytometry.

Administered solo overnight clinical diagnostic testing. Calibrated multi-channel physiological montages (EEG, EKG, EMG, EOG), monitored live data streams for real-time respiratory and cardiac anomalies, and synthesized diagnostic clinical reports for physician review.

Generated daily personnel readiness and accountability reports for a 900+ Marine unit at Camp Pendleton. Managed secure distribution logistics serving 800+ personnel, processed command awards, and directed rear-detachment operational support during combat deployments.

Evaluated epidemiological co-infection surveillance data comparing single-site versus extragenital 3-site screening efficacy. Maintained longitudinal data integrity across a cohort of 600 HIV-positive patients and 4,000+ diagnostic test results. Cleaned and structured clinical databases, calculated Odds Ratios and statistical significance in IBM SPSS, and co-authored findings published in the Medical Surveillance Monthly Report (MSMR):

"Evaluation of Extragenital Screening for Gonorrhea and Chlamydia in HIV-infected Active Duty Air Force Members" ↗

Executed Polymerase Chain Reaction (PCR) protocols for DNA isolation and genotyping. Ran agarose gel electrophoresis, compounded chemical fixatives, and performed histological tissue processing, microtomy, and specialized staining of CNS specimens under sterile biosafety conditions.

Concentration in advanced diagnostics, flow cytometric immunophenotyping, immunohematology, and laboratory management. Preparing for the ASCP Medical Laboratory Scientist (MLS) board certification examination.

Completed 4 years of intensive upper-division laboratory sciences (including biochemistry, genetics, cellular biology, and physiology), building the scientific baseline and technical laboratory prerequisites for graduate clinical diagnostics.

Architecture of full-stack web applications and database systems using JavaScript, Node.js, Express, and MongoDB.

Quantitative study of disease transmission, biostatistical analysis, public health surveillance methodologies, and community health interventions.
