professions of mechanical engineering. The program also provides continuing education in
advanced subjects for the working engineer who acknowledges the need to stay abreast of the
rapidly changing technological world. Emphasis is placed on the development of the engineer’s
capacity for independent study and continued professional growth.
DEGREE OFFERED
The program offers a Master of Science in Mechanical Engineering degree.
ADMISSION REQUIREMENTS
- Applicants must have earned a Bachelor’s degree in Mechanical Engineering from an ABET-accredited program or its equivalent with a QPA of 2.5 or better.
- Applicants without the appropriate Mechanical Engineering degree may be admitted and required to take additional course work as determined by the program director.
- Applicants must submit the following:
• Completed application

CURRICULUM
The student will be assigned an initial advisor through the academic approval sequence. The
advisor and the student will select appropriate courses for the objectives of the student and
obtain approval of this curriculum through the academic approval sequence. Within the first 12
credits, students must take the following two courses.
GENG 603 Engineering Analysis 1
GENG 703 Engineering Analysis 2
Note: A student may replace GENG 603 Engineering Analysis 1 with another approved GME or GENG
course by passing an exam conducted during the first week of class. The exam time will be
announced at the first GENG 603 class.
After the student has completed 12 credits of study, the student will be assessed relative to
their preparedness to begin thesis or project work. The candidate must have a 3.0 QPA to
continue for the degree. The candidate must then choose one of the three project/thesis plans
below for completion of their degree; an advisor will be assigned to guide the candidate for the
completion of the degree work.
The advisor (thesis or project) will recommend a program of study and advise the student
regarding the thesis/project subject, act as the academic advisor, and determine when to
recommend the student for final examination, at which time this recommendation will be
transmitted for approval through the academic approval sequence.
Plan A (Thesis)
The student will be required to submit a six credit thesis as part of the 30 credits of graduate
course work and pass a final oral examination on the thesis material and related subjects. The
thesis work must be approved by the academic approval sequence prior to the commencement of the
research work. The thesis advisor will direct the student’s work and determine when to recommend
the manuscript for review by a faculty committee. The review committee will be appointed by the
usual academic approval sequence and will consist of three full-time Gannon Mechanical Engineering
faculty members familiar with the subject material. In some cases, one committee member may be
from outside the Mechanical Engineering Department. The advisor will be the chair of the review
committee.
Plan B (Project)
The student will be required to complete a design project and to pass a final oral examination
covering the student’s project and related subject areas. The project will be worth three
graduate credits as part of the 30 credits of graduate work. The project must be approved by the
usual academic approval sequence prior to the commencement of the project work. The project
advisor will direct the student’s work and determine when to recommend the manuscript for review
by a faculty committee. The review committee will be appointed by the usual academic approval
sequence and will consist of three full-time Gannon Mechanical Engineering faculty members
familiar with the subject material. In some cases, one committee member may be from outside of
the Mechanical Engineering Department. The advisor will be the chair of the review committee.
Plan C (Project Course)
The student will be required to complete a three credit course designated as a project course as
part of the 30 credits of graduate work. The project course will be approved by the usual
academic approval sequence prior to the commencement of the course and must include a significant
project for its completion. The course instructor will inform the student of the complete
requirements for the project course and will be responsible for seeing that the student satisfies
these requirements.
Professional Track (Work-Study Program)
The objective of the professional track is to present an academic program combined with
application training on actual industrial problems to give students a targeted education,
complemented by hands-on, real-world development exposure. Students are selected for this track
based on academic background, leadership skills, and communications skills. The student is
assigned a Gannon professor as a mentor while working at the industrial site. The mentor advises
the student on his academic work and guides the student on industrial engineering projects. The
projects are carefully chosen to reinforce classroom work and to develop students into outstanding
engineers. In addition to the mentorship in technical areas, the professor also mentors the
student in leadership skills, work and personal ethics, and communication skills that are needed
in the industrial workplace. The student is also assigned an engineering mentor from the
industrial sponsor. This track requires that the student work on these projects half-time during
the school year and full-time during the summer. The number of students in this track is
dependent on availability of industrial sponsorship.
