Your partners in growth and success

KPATH Scientific, LLC

We are passionate about building solutions and products that solve important problems, and building teams who are equally passionate about achieving those goals. We launched KPATH Scientific, LLC to let us transfer what we have learned in industry and research to the companies who can benefit most from experienced guidance.

We bring diverse engineering, scientific, product and managerial experience and domain expertise to bear on problems facing many high-tech startups and growing companies.

The name KPATH comes from a system LLNL built after the 9/11 attacks to fully automate the design of PCR signatures to detect any microbial ​organism for which a full genome was available. While it may appear to mean "thousands of pathogens", it actually was meant to resemble the call sign of a radio station ("You're listening to KPATH: The pathogen hits of yesterday and today; all pathogens, all the time!") Establishment of the KPATH system in 2003 just in time to aid the CDC to create an assay for the SARS outbreak helped brand the LLNL pathogen bioinformatics team as a leader in applying advance genomic analyses in the service of biodefense and public health.

Tom Slezak 
Co-founder and CEO

A computer scientist by training, Tom is a recognized expert in pathogen detection and biosecurity. He has served on 5 National Academy of Science committees since 2009 (most recently: Biodefense in the Age of Synthetic Biology, 2018) and regularly is called upon by the CDC and other agencies to consult. This included co-chairing the 2011 Blue Ribbon Panel on bioinformatics for the CDC that directly led to Congressional funding for the Advanced Molecular Detection program, and twice chairing the NIH/NIAID proposal review committees that evaluated proposals for major 5-year Genome Sequencing and Infectious Disease centers contracts. In May 2020 Tom was one of 4 people the CDC asked to review their new COVID-19 + Influenza A/B multiplex assay prior to submission to the FDA for Emergency Use Authorization. EUA was granted in July 2020 and this assay is now in use by public health labs nationwide.


For over 30 years Tom has also done independent bioinformatics consulting and management coaching. Clients have included pharmaceutical, sequencing, point-of-care PCR, CRISPR gene editing, and microbiome companies, plus research institutions, hospitals and government agencies. Engagements have ranged from single-day to multi-year and have included bioinformatics information system design, recruiting and hiring assistance, and coaching beginning and experienced managers. Tom is currently on the board of directors for LexaGene, a point-of-care PCR startup in Boston (2016-); he consulted for Inscripta (2018-2022), 10X Genomics (2014-2016), and he is an advisor for several nascent biotech startups.


Prior to starting his own consulting firm in 2018, Tom spent decades of applying computer science and team building/managing in support of leading-edge biological research and active biodefense at Lawrence Livermore National Laboratory (LLNL). This includes 14 years building bioinformatics systems to support the physical mapping and sequencing of human chromosome 19 as part of the Human Genome Project. Tom was also part of the team that designed, built and continues to support the nationwide BioWatch system since 2003. The LLNL bioinformatics team Tom led has been focused on improving ways of detecting and characterizing dangerous pathogens since they first started building a wide-area biodetection system for use at the 2002 Winter Olympics. Tom secured and managed over $75M in bioinformatics contracts (2000-2018) from DHS, DoD, DOE, and other federal agencies.

Tom's LLNL bioinformatics team pioneered the use of fully-automated computational genomic analyses to design the DNA signatures for PCR assays. Since 2000 the LLNL team worked with researchers at the CDC to improve detection signatures for many pathogens, including the causative agents of anthrax, plague, tularemia, SARS, monkeypox and smallpox. In 2003 they responded to an outbreak of Newcastle disease virus in poultry in California, developing a new PCR diagnostic to speed the diagnosis time from 6-12 days down to 4 hours. They subsequently automated the design of multiplex PCR signatures and built the first microarray to detect all sequenced bacteria and viruses at the whole-genome level. In recent years, the latest versions of this array can process 24 or 96 samples in parallel, each sample being exposed to 1.4 million DNA probes that have been designed computationally to detect over 12,000 unique species of bacteria, viruses, fungi, archaea, and protozoa. The LLNL team has also developed DNA sequence analysis software for complex clinical or environmental samples (LMAT, the Livermore Metagenomics Analysis Toolkit) and targeted sequencing panels for improving the detection of biothreat agents and antimicrobial resistance.
