On August 19, 2011, David and Kelley Choi became the proud parents of beautiful baby girl Hannah Jiyeon Choi. Hannah arrived at a healthy 7 lbs and 9 oz, and 19 3/4 inches.

Not long after Hannah's birth, David and Kelley relocated to Maryland so that David could begin his post-doctoral fellowship at NASA's Goddard Space Flight Center.

Hannah has grown quite a bit from her newborn portrait (shown here)---she is even cuter now, if that's possible.

Best wishes to David, Kelley, and Hannah!
