Meredith Rodney McKay

Meredith Rodney McKay, better known as Rodney McKay, due to his dislike of his real first name (he is called 'Meredith' or 'Mer' by his sister and briefly 'Rod' by Dr. Daniel Jackson), is a male Human who is a brilliant astrophysicist, and one of the leading experts on Ancient and nanite technology.

Although he is able to formulate many ground-breaking ideas on a broad range of subjects, his phobias and arrogance continually serve as a hindrance to people acknowledging his abilities.

McKay was initially involved with the Earth Stargate Program and later became the leading scientist on the Atlantis Expedition. He is a self-important scientist with a great deal of knowledge but, according to Colonel Samantha Carter, has no feel for it.

When he joined the expedition to Starbase Atlantis, he was very eager to be part of the expedition and he continues to excel in many scientific aspects. He is also a member of the First Atlantis Reconnaissance Team. Despite his mannerisms and insecurities, he does occasionally show endearing moments of vulnerability and bravery. Together with Dr. Radek Zelenka, he works miracles with the tools at hand, but he has trouble acknowledging other people's work.
