About Us
Mission Statement
Nelson Scientific Labs is a Maryland based biomedical research and consulting company founded in 2018. We discover, develop, and deliver biomarkers for radiation exposure assessment, in vitro diagnostics and precision medicine. We acquire and study molecular profile data from diverse biological matrices using state-of-the-art analytic platforms for metabolomics, transcriptomics, and proteomics. We offer hope to cancer patients seeking early disease detection and health monitoring during curative radiation therapy by providing valuable solutions for personalized treatment and precision medicine that improve patient outcomes.
Nelson’s mission is to use personalized medicine approaches for improving clinical outcomes in cancer patients receiving curative radiation therapy. In order to attain this goal, we have developed strategic collaborations that combine inter-disciplinary programs including molecular profiling, clinical chemistry, bioinformatics and clinical care and treatment. Nelson has focused on biomarker panels for precision medicine in early detection of cancer and for prediction of radiation induced late effects and/or organ dysfunction.
Company Goals
At Nelson, we strive to break barriers in early cancer detection with kit-based susceptibility biomarkers for pancreatic cancer and late health effects of ionizing radiation exposure. These precision medicine tools will facilitate early decision-making, guide treatment options, and improve patient outcomes. Bringing these tools to market will require rigor, diligence, and expertise. To that end, we have assembled an experienced, engaged, multi-disciplinary team dedicated to developing and implementing novel study designs and cutting-edge analytics for biomarker exploration and development. We are one of the first biotechnology companies focused on the use of multi-omics approaches for predicting ionizing radiation late health effects and early detection of pancreatic cancer.
Our Culture
At Nelson, our mission is to launch kit-based biomarker assays as “In Vitro Diagnostics” with the goal of identifying sub-populations at risk of developing pancreatic cancer as well as those at risk of experiencing late effects following accidental or therapeutic exposure to ionizing radiation.
Notable Accomplishments:
- Early adopters of liquid chromatography-mass spectrometry metabolomics
- Foundational pioneers in biomarker discovery and validation for Delayed Effects of Acute Radiation Exposure (DEARE)
- Use of a blood-exosome-based liquid biopsy approach for building predictive algorithms for early detection of pancreatic cancer
