    Expertise

    Jo Hardin鈥檚 areas of expertise include statistical analysis of high-throughput genetic data which don鈥檛 conform to technical conditions in standard methods. She works on problems of normalizing data structures, clustering and classifying time course profiles and creating metrics to measure a variety of signals.

    Hardin chose to become a statistician because of the myriad potential collaborations across many fields.  She has worked with medical doctors, biologists, geologists, physicists, and mathematicians in her research, and the majority of her research publications are co-authored with undergraduate students. Through new ventures into data science (both research and teaching), she is currently exploring ways that today鈥檚 extensive data (both in scale and in occurrence) are shaping science and the world around us.

    Hardin is deeply committed to creating open and accessible ways for engaging in statistics, data science and mathematics. She has co-authored an open access textbook, , and posts all of her publicly. Through local (e.g., Pomona鈥檚 own PAYS and Pomona Scholars of Math [PSM] programs) and national (Posse) endeavors, she works to lower barriers to access to college, with particular focus on statistics, data science and mathematics.
