Tarek Al-Aydi, a medical sales executive, specializes in spectroscopy, which studies how light interacts with matter to reveal physical properties. In medicine, spectroscopy uses energy sources, like lasers, and measurement devices to analyze samples. This process involves directing light through various components to measure the changes in frequencies after interaction with the sample.

2. Introduction
Based in New Jersey, Tarek Al-Aydi is a longtime medical sales executive who has held team
leadership responsibilities with companies such as Thermo Fisher Scientific and Metrohm
USA. With the latter firm, Tarek Al-Aydi served as a titration and spectroscopy specialist.

3. As a discipline, spectroscopy deals with how light disperses into a variety of component
energies. An understanding of how forms of electromagnetic radiation, from fluorescence to
UV light, interact with matter allows health care professionals, as well as professionals in
disciplines such as astronomy, to infer physical properties about an object.

4. Within the medical sphere, spectroscopic analysis involves the use of instruments that emit
an energy source and are paired with a device that measures how that energy source
changes after interacting with a sample. In most cases, the energy source is a laser, but ion
and radiation sources also exist. Results are generated by directing light through an entrance
slit, lens, and light dispersing prism, with an exit slit allowing frequencies to escape that are
measured and analyzed.
