Kun (Karen) Zhang received her PhD in Computer Science from Tulane University in 2006 and has been working as Assistant Professor at Xavier University of Louisiana since then. Her main research interests and experiences are in various areas of data mining and bioinformatics. She is particularly interested in developing simple, unconventional, but effective methods to solve challenging real-world problems. Her first-authored paper that uses "Randomized Decision Tree" to predict skewed ozone days won “the best application paper award” at the IEEE 6th International Conference on Data Mining (ICDM2006). An extended version further comparing Probabilities Estimation Trees (PETs) with SVM, Bagging, AdaBoost and a number of other popular learning algorithms on the same domain was published at the prestigious data mining journal Knowledge and Information Systems. Her later application of PETs to the nuclear radioxenon monitoring problem won the championship of the 8th IEEE ICDM2008 Data Mining Contest. Dr. Zhang is the junior faculty recipient of the 2010 Norman C. Francis Excellence in Scholarship Award. Her current bioinformatics research is funded by National Institution of Health, Louisiana Broad of Regents and Tulane Cancer Center. Dr. Zhang has established fruitful collaborations with investigators having mutual interests and complementary expertise at IBM T.J Watson Research Center, Tulane Cancer Center, University of New Orleans and University of North Texas. She is the member of ACM, Louisiana Cancer Research Consortium and Louisiana Biomedical Research Network.
