Selected Student Quotes

"Very people–oriented person. I always got the feeling that you thought about what was best for the class behind the scenes. It seems like you had to make a variety of critical decisions, and I definitely felt like you were doing well at navigating those decisions. I hope for the sake of future students that you decide to teach." - Student in Social Psychology Lab (Spring 2020)

"She was very kind and really went out of her way to help us, especially after we switched to online classes [due to COVID-19]. She put a lot of time and effort preparing videos and making sure we had all the information we needed so I really appreciated it." - Student in Social Psychology Lab (Spring 2020)

"Katie was excellent at explaining things and elaborating on topics we learned in lecture. Her feedback on assignments was very thorough and helpful, it was very clear where you missed points and why you got the grade you got. Overall, great instructor." - Student in Statistical Techniques (Fall 2019)

"Katie was very helpful in and out of class. She was very responsive and helpful with emails concerning lab assignments, and walked around the room during class to help students as necessary. She managed this class very well, which made it a low–stress environment for me. I was really apprehensive coming into this course, but it turned out to be much better than I expected, thanks to discussions during labs and Katie's help in and out of class (especially the Canvas feedback)." - Student in Statistical Techniques (Fall 2019)

"Katie is one of the best instructors I have ever had the pleasure of having. She was great at explaining the materials and subjects we had to learn. She was always available during and after class which is impressive to say the least. She is super busy as a grad student and will still make time in her busy schedule to help her students. Not many professors, much less grad students will take the time to do that. She really understands the material and explains it so well that someone who has no idea how any of this works, understood to a certain extent. I wish I would have found more time to get help from her, because when I did I felt much more knowledgeable and prepared for assignments, class, and exams. Katie is an amazing instructor and an even better person. Indiana University should hire her full time before she goes somewhere else." - Student in Statistical Techniques (Fall 2019)

"She seemed very invested in us students. She is very good at responding quickly and very efficiently to my questions in emails, and in class she is very sweet and helpful. I always felt that she was very much on our side and genuinely wanted us to do well in the class." - Student in Statistical Techniques (Fall 2019)

"She cares a lot about the success of her students. She provides as much help and feedback as possible. She makes sure all concepts are understood, and is very available if someone needs help." - Student in Methods of Experimental Psychology (Spring 2017)

"I love how fast you get back to questions or concerns about the class. You care about the success of your students and that makes this class a lot more enjoyable. Your feedback on our papers and homework is extremely helpful. Overall, I think the course is great and I actually feel like it will help me significantly in the future." - Anonymous Student in Methods of Experimental Psychology (Spring 2017)
