CONTENTSAbout MeResumeMain CoursesProjects

I am an international student from China. Strongly desired to be a Mechanical Engineer, I'm focusing on the design & control area of study. With the proficient Solidworks, Mathematica, MatLab, FEA software skills, I'm devoting myself into three projects--Racecar, Elder Care Robot and Bat Robot Design.

Main CoursesENGRMAE 245 SPATIAL MECHANISM DESIGN

Fundamental kinematic theory required for planar, spherical, and spatial mechanism design. The focus is on algebraic methods for the exact solution of constraint equations.

ENGRMAE 270A LINEAR SYSTEMS I

Input-output and state-space representations of continuous-time linear systems. State transition matrices. Controllability and observability. Irreducible realizations. State feedback and observer design.

Main CoursesMain CoursesENGRMAE 241 DYNAMICS

Kinematics and dynamics of three-dimensional motions. Lagrange's equations, Newton-Euler equations. Applications include robot systems and spinning satellites.

ENGRMAE 244 THEORETICAL KINEMATICS

Spatial rigid body kinematics is presented with applications to robotics. Orthogonal Matrices, Rodrigues' formula, Quaternions, Plucker coordinates, screw theory, and dual numbers are studied using modern projective geometry and multi-linear algebra. Applications include trajectory planning, inverse kinematics, and workspace analysis.

Main CoursesENGRMAE 152 INTRODUCTION TO COMPUTER-AIDED ENGINEERINGElements and principles of computer-aided engineering with modern hardware and software are presented with a design focus. Case studies are used to assist in finite-element method techniques.

Main Courses

BME 295 CARDIOVACULAR DEVICES

This course aims to familiarize the graduate students with technical and real-world aspects of cardiovascular devices. World known experts will discuss about multiple aspects of cardiovascular devices.Topics to be covered are: cardiovascular device engineering, regulatory affairs, fundraising, patents, commercialization, clinical applications, marketing and so many more.

ENGRMAE 249 MICRO-SENSORS AND ACTUATORS

Introduction to the technology of Micro-Electro-Mechanical Systems (MEMS). Fundamental principles and applications of important microsensors, actuation principles on micro-scale. Introduction to the elements of signal processing; processing of materials for micro sensor/actuator fabrication; smart sensors and microsensor/microactuator array devices.
