Personal life
Prof. Lemos's life has been shaped by his unique upbringing and strong family support. As the youngest in a Greek family, he traveled on cargo ships with his father, fostering cultural diversity. Growing up in 70s Greece, he developed resilience and a drive for new paths. Balancing personal life and a demanding career, he credits his success to family and community, achieving milestones like board membership in a top forensic toxicology association and a Congressional proclamation. His partner of over ten years provides crucial support, helping him tackle new projects with renewed energy.

Education

Prof. Lemos began with biology, discovering forensic chemistry under Prof. Nicholas John Mayer. His journey led to a master's at John Jay College and a PhD in Glasgow, specializing in postmortem investigations. Mentors like Prof. Arvind Agarwal and Prof. Peter Deforest shaped his scientific acumen, while Dr. Peter Vanezis broadened his expertise in human performance toxicology.

Research impact
Prof. Lemos has made significant strides in analytical toxicology, aiming to make the justice system more equitable and accessible. His innovative research includes the ability to determine whether cannabis presence is due to handling or actual use through nail analysis. Notably, his 2011 publication on post mortem cannabis analysis demonstrated that blood concentrations in deceased individuals cannot reliably indicate intoxication or impairment, a revelation due to post mortem redistribution. This finding has reshaped forensic and legal practices globally, ensuring accurate interpretations and safeguarding against wrongful convictions.

Public engagement
Prof. Lemos champions LGBTIQ+ outreach, founding and chairing the diversity committee at the American Academy of Forensic Sciences. He promotes safe spaces, identity acceptance, and encourages researchers to thrive post-coming out. He turns challenges into scientific innovation, embodying the community's spirit.
