10 University of Nebraska-Lincoln (UNL) History UNL was chartered in 1869 and is recognized by the Carnegie Foundation as a Doctoral/Research Intensive university (among only top 2% of U.S. institutions). The University of Nebraska-Lincoln was the first institution in the American West to grant the Ph.D. degree. In 2011, UNL joined the Big-10 athletic conference and the Big-10 Committee on Institutional Cooperation. The University of Nebraska-Lincoln is a member of the Fulbright Association. In fact, one of the so honored students graduating this spring, Mallory Slama, is now teaching English as a foreign language in Bilovec, Czech Republic. Her home town is Tábor, South Dakota. The University of Nebraska has 3 Nobel Laureates as Alumni

26 Current Departmental Information on Graduate Students Direct PhD option available (after B.S. degree) with high priority of receiving financial aid Total of 80 graduate students in EE –20 Masters Students – 60 PHD students –56 have Research Assistantships (48 PhD, 8 MS) –15 have Teaching Assistantships (12 PhD, 3 MS)

27 Approximately 170 students have applied to our graduate program for admission since Fall 2011 30 were admitted full and unconditionally and 10 were admitted to the Masters program since Fall 2011 We have admitted Students from the following institutions: 1.Polytecnico di Milano, Milan, Italy 2.Leipzig University, Leipzig, Germany 3.Bogaziçi University, Istanbul, Turkey 4.California Institute of Technology (Cal Tech), Pasadena, California, USA 5.Tsinghua University, Beijing, China 6.Huazhong University of Science and Technology, Wuhan, China

28 Funding/Scholarship Opportunities for PhD Students  Research Assistantships (RA): Sponsored by Thesis Advisor  Teaching Assistantships (TA): Sponsored by Department  Fellowships + tuition remission (Part of TA/RA)  Additional merit based fellowships (extra income)  Thesis Dissertation Research Awards, Travel Grants (both domestic and international travel for conference attendance and paper presentation)  Graduate student paper competition  Student who are eligible for assistantships could receive a generous stipend for working, as well as tuition and health insurance benefits  Fast track application for Czech students: Waive application fee, waive GRE

29 Benefits of an assistantship A new PhD student receives a stipend of $18,000.00 per year (≈ 360,000 CZK) In addition about $3,100 (≈ 62,000 CZK) is paid each semester for your tuition and About $500 (≈ 10,000 CZK) is paid for your health insurance each semester. Thus, each year about $25,000 (≈ 500,000 CZK) are the benefits to you if you have an assistantship. It is also possible that this could be increased with Fellowships. The fast track application from the last slide is granted to those who receive a recommendation from someone such as me or Drs. Hubička, Olejníček, or Kment.

30 For a Successful PhD Career Choosing an Advisor: Mutual relationship with common research interests and responsibilities (for both TAs and RAs). For RAs, advisor is the RA sponsor, whereas for TAs, since the sponsor is the Department, students who obtained a TA have one semester to decide who to work with as an advisor. Fulfilling the Assistantship requirements: Departmental Teaching Assistantships (TA) may have extra load whereas Research Assistantship (RA) is contingent upon the availability of funds from research grants. PhD students with TAs can have up to 4 years of support with less load initially. Fulfilling the PhD program credit requirements: Total of 90 (for both TAs and RAs) credit hours with a flexible distribution of research and course work. The balance of research and course work to be determined via Thesis Supervisory Committee.

31 Keeping the Advisor/Student relation intact: Planning of coursework and research guidance have to be consistently executed throughout the semesters. Becoming an independent researcher: Expected toward the end of studies. This is evidenced by: –Developing innovative ideas and solutions to the research problem at hand, –Authoring conference and journal papers based on the results of research, –Taking part in graduate student paper competitions, –Making use of Graduate Student Travel Grants to attend International Conferences and present papers, –Participating in authoring research grant proposals –Possibly supervising an M.S. or a senior undergraduate student working in the research lab Teaching Experience: Opportunities exist for senior PhD students to either teach a class or instruct a lab. This is beneficial if the PhD candidate is targeting an academic career.
