Lynn is a law professor at the University of Texas, and frequently serves as a consultant to other attorneys on issues of legal ethics in mass tort settlements. A graduate of Yale Law School and Yale College, she also holds a degree from Oxford University, which she attended as a Marshall Scholar.

A 16-time NABC Champion, Lynn's work commitments largely limit her tournament play to NABC and European Open Events.  In 2014, Lynn won her first World Championship, the McConnell Cup in Sanya, China. She won the McConnell Cup again in 2018 in Orlando, Florida, and won a bronze medal in 2022 in Wroclaw, Poland. She has represented the US in the Venice Cup five times, winning a silver medal with USA I in 2009 (Sao Paulo, Brazil), and finishing 5th in 2023 (Marrakech, Morocco), 2022 (Salsomaggiore, Italy), 2019 (Wuhan, China), and 2001 (Paris, France). In 2015, she was on the winning Women's Team in the European Open Championships (Tromso, Norway), and finished second in the same event in 2023 (Strasbourg, France) and 2017 (Montecatini, Italy).

A lifelong athlete, Lynn rowed for the Yale Varsity Women’s Crew and was selected to one U.S. Olympic and three National Women’s Rowing Team training camps during college. An avid downhill skier and runner in recent years, she has completed four marathons. She lives in Austin, Texas with her husband, Sam Dinkin, and two cats, Reginald and Babycat.

Inducted into the ACBL’s Hall of Fame in 2007, Kerri is a nine-time world champion. She has won at least one World Championship in each of five consecutive decades, a record of “longevity at the top” equaled by few players. Indeed, one wonders if anyone in any competitive endeavor outside of bridge has, or could, come close to that record of sustained excellence.

Although (because?) her parents played bridge, Kerri swore she never would. But, she finally succumbed during her sophomore year at Miami University in Ohio, and played her first local duplicate with her father. She soon moved to California, where she credits many experts for helping her during her early years as a player: Mike Shuman, Harold Guiver, Mike Smolen, Hermine Baron, Harold Kandler, Rhoda Walsh, and, most significantly, Barry Crane.

Kerri’s first victory at the world level was the 1978 Mixed Pairs in which she and Barry Crane bested a world-class field by an astonishing margin of 5 boards. During her highly successful 14-year partnership with Barry, she was responsible for buying his coffee (2/3 of a cup, black) and filling out the convention card, while he handled the travel arrangements. Kerri’s five subsequent world championships were won in partnership with Karen McCallum (1989, 1990, 1993) and Irina Levitina (2002, 2006). Her most recent world championships were a repeat Mixed Pairs win, this time with Jie "Jack" Zhao in 2014, the World National Women's Teams in 2016 and the McConnell in 2018.

A full-time player beginning in the early 1970s, Kerri changed careers in 1988 when she began trading options full-time on the floor of the American Stock Exchange. She retired in 2001. An avid golfer, Kerri lives in Delray Beach, FL, with her husband, Steve, and cat Brooke.
