Welcome to the Spring Semester!

Welcome back! We hope you all had a restful break and are ready to tackle the spring semester. Here are a couple of events to look forward to in the next couple of weeks!

Potluck Party
We will hold a potluck party on NEXT Friday, January 23rd, from 11:30 to 13:30 in CH212. All the faculty, staff, and students are invited to bring their best dish. Even if you don’t get a chance to prepare one, please feel free to come and enjoy the food from around the world. To make it more fun, we will vote for the Best Entree, Best Salad, Best Dessert, and Best Vegetarian Dish after the party. A beloved department t-shirt will go to each winning chef.
Internship Info Session
Looking for an internship for the summer? We will be holding a student seminar where your fellow graduate students will share their previous internship experiences. You will get information on where to look for internships, how to apply, and what you can hope to gain from a summer internship. This will be held on February 3rd at 11:30 in CH 212. More details will be forthcoming, but save the date!
Department T-shirt Design Contest
We will be holding our annual department t-shirt design contest, where students will submit their designs and the department will vote on their favorite. Look for an email with more details about the competition.

Good luck on exams!

As a busy semester draws to a close, we’d like to take this opportunity to wish everyone good luck as they finish exams and projects. Just a few more days, and it will be time for a well-deserved break. Finish strong!

Happy Holidays!

Positive energy from our graduates

New school year has began. How is everyone doing?

Before we get drowned into our busy school life in no time, our four excellent graduates from the program, Xin, Cindy, Wei and Xiaoxi, are here to provide us some with positive energy. They have all graduated before last summer, and let’s listen to what they would like to say to us!



Welcome to the 2014-2015 school year!

It’s that time of year again! First, on behalf of the entire department, we wish to extend a warm welcome to all incoming students, and to welcome back all returning students.

Our first official department social event this past Sunday was a great success! Faculty, students, and their families came out for great conversation and Graeter’s ice cream. Nothing puts smiles on statisticians’ faces like free ice cream, courtesy of the Statistics department.

Andrew Olsen

I am fourth year Ph.D. student working with Radu Herbei. My research revolves around Markov Chains and their convergence. I have lectured Stat 1450 for two years. Outside academia, I have interned with Abbott Laboratories and JPMorgan Chase, and will be an intern this upcoming summer for Capital One. I am married and have two cute little kids, and I love spending free time with them.


Ran Wei 057

Ran Wei (also known as Wendy)

I’m a fourth year Ph.D. student and am doing research on data mining, social network analysis and network sampling. I’ve been working as a research assistant, teaching assistant and statistical consultant in the department for my past graduate experience. I’ve done a summer intern at a local IT company called Manta and am going to spend my summer at Twitter as a data scientist intern this year.

Outside academic life, I enjoy all kinds of music, sports and fun stuff. You can find more about me from an earlier post on the department student blog: https://u.osu.edu/cmool/2014/01/26/is-it-spring-yet/



Jojo Wang & Marie Ozanne

Dear students,

Over the past year, we have been inspired by the dedication and creativity former co-presidents Mark Risser and Staci White have brought to the position. We plan to continue important traditions and events started by them, while introducing a couple new ideas of our own. Specifically we plan to:

  1. Maintain the online “student blog”, to chronicle student research and activities for current and prospective students
  2. Continue the annual department t-shirt tradition
  3. Continue holding student seminars to:
    1. Allow senior students to share research interests and advisor information with students who have yet to choose a research area/advisor
    2. Have recent graduates discuss their current careers in both industry and academia
    3. Eat pizza
    4. Organize social events, including:
      1. Ice cream social at the beginning of the school year to welcome incoming students
      2. Happy Hour on Fridays throughout the school year
      3. Department potluck so that we can appreciate the cultural diversity of our department through our culinary creations
      4. Offer course and qualifier advice to younger students

As students from different class years and cultural backgrounds, we hope to use our collective experiences to serve the entire student body, staff, and faculty in the upcoming year. Thank you for your consideration,

Jojo and Marie


Is It Spring Yet?

Hello everyone,

Hope you are staying warm in this miserable winter weather — only 52 days left until Spring! Now that we are a couple of weeks into the semester, I’m sure everyone has tons of homework/research to do to keep them occupied!

Student Profiles

We are pleased to feature Agniva Som and Wendy Wei as our latest student bios!


Hello, I am Agniva Som, a fourth year PhD candidate in the Statistics department.  Those people who might struggle to say my name properly can call me Som while a lot of friends call me Tommy, which is also fine by me.  I come from the ‘slightly’ populated city of Kolkata (only 14 million people living there) located on the east side of India. Before joining the department, I got both my Bachelor’s and Master’s degrees in Statistics from the Indian Statistical Institute in Kolkata.

I am working with Dr. Chris Hans and Dr. Steve MacEachern on Bayesian modeling and variable selection problems for my dissertation.  I enjoy research and hope to remain involved with it even after graduation.  Life in graduate school has been a great and quite fun experience for me so far and I have been really fortunate to make some wonderful friends here.  I like hanging out with friends and find it particularly appealing to take a night off every now and then to go out with friends from within or outside the department (a big thank you to all the different social chairs and presidents).

I am an avid fan of soccer and love watching games from the English Premier League and the European Champions League. The only bad part is that the time difference between the countries in Europe and the United States can sometimes force me to wake up quite early to watch games, and this happens too frequently for my liking.  The team I support the most is Manchester United, but let’s not discuss their performance this year. I haven’t really been playing sports myself for a few years now, but I loved playing soccer and cricket when I was back in India. I also enjoy sleeping (a LOT), watching movies and eating good food.


Hello everyone! My name is Ran Wei and my English name is Wendy. I’m currently a fourth year PhD student in Statistics. My research interest includes data mining, sampling methods and social network analysis. I’m working with Prof. Tao Shi. on these topics.

I’m originally from Hubei Province, China and came to OSU after I got my bachelor’s degree in statistics at Zhejiang University. Zhejiang University is located at Hangzhou, a city famous for a beautiful lake called ‘West Lake’, even though this city is actually at EAST coast of China, only about 100 miles south of Shanghai.

I’m currently working as a consultant in the Statistical Consulting Services (SCS) in the statistics department. I like the experience a lot. Just as the famous quote from John Tukey says “The best thing about being a statistician is that you get to play in everyone’e backyard”, the thing I like the most about my consulting work is that I get a chance to look at and understand datasets from various fields and backgrounds, including agriculture, biology, social work, linguistics, women’s study and even music! Before working as a consultant, my previous working experience includes being a research assistant joint with the Department of Transportation and Department of Statistics, teaching assistant of STAT 1430 and STAT 2480, and a summer internship.

In addition to diving into the world of statistics and data, I’m trying to make my life as colorful as the world of statistics. As an outgoing person, I enjoy hanging out with friends and getting to know different people and culture. Like many people, I enjoy traveling and music. I travel a lot and road trips are my favorite part. I’ve been to different types of concerts (domestic or international, tours, shows, music festival, etc) enjoying the enthusiasm singers brought to audience. Sport is another big thing in my life. Ice skating, swimming, yoga, badminton and table tennis are in the list of my favorite sports. I enjoy outdoor activities and I like adventurous sports a lot. People have once asked me why I have Wendy as my English name. The reason is that the first time I heard about this name was when I was watching the movie ‘Peter Pan’ back in middle school and I like that movie a lot. Later I checked a dictionary for English names and it says that ‘Wendy’ means a girl who loves adventuring. This makes me like the name more. Last year I took a skydiving course offered by OSU and finished my first AFF skydiving (http://www.youtube.com/watch?v=W0P9P16mgCI ) at Middletown, OH. It was a very unique and exciting experience that I would encourage anyone who is interested to take the chance during the stay at OSU since there aren’t many universities that would offer a skydiving course. Surely there are more uncertainties to be explored both inside and outside the statistics world. Hope everyone enjoys this exciting and challenging journey at graduate school!

Welcome Back!

Hello everyone,

I hope you had a great winter break and enjoyed your extra two days off! It looks like it’s going to be a cold semester, so thankfully the radiators are fixed in Cockins Hall! Here is a comic that seemed appropriate for the start of a new year.

Mark and I want to get the Student Seminar Series up and running again, so if you have any ideas for a seminar you would like us to host, please let us know. Also, best of luck to everyone who is taking MAS/Qualifying exams soon.

Have a great first (half) week back!

Check it out — OSU student Andrew Bean made the front page of the Wall Street Journal!!

Says Andrew, “I definitely didn’t expect to ever make the front page of the Wall Street Journal, let alone for something so auspicious as losing my fantasy football league.” Congrats — this is definitely CV material!

Student Seminar Series (SSS) 2 a success

Last week, we hosted our second SSS event of the semester, this time focusing on department computing resources. Once again lured by the free pizza, a large group of our students gathered to learn more about the computing resources available to them here in our department. Specifically:

“Top five things to know about computing as a first-year student” (by Mark Risser)

“Web Resources and You” (by Tom Marker)

“Lord of the Rings and Statistical Computing: How to Harness the Computational Power of the Middle Earth in your Research” -or- “A Tutorial of Using Departmental Computing Resources” (by Andrew Olsen)
















Stay tuned for more SSS events in the spring!

Mark and Staci
