Contact Information

I am a PhD candidate working on MRI-compatible robotics and image-guided surgery. I am currently involved in developing fiber optic force sensing and teleoperation of Piezoelectric Driven Needle Placement Robot for Prostate Interventions and two side projects on MRI-guided robotic neurosurgery and Humanoid Robot for Autism Interventions in Children.

I did three month intern at Mitsubishi Electric Research Laboratories in 2012 summer. I worked on prostate robot design and image analysis at Surgical Planning Laboratory of Harvard Medical School and Brigham & Women's Hospital in 2010 summer. I studied robotics ( mobile manipulation) with Professor Venkat Krovi at State University of New York Buffalo. I obtained B.S. degree in Control Science and Engineering from Harbin Institute of Technology, China in 2006.

    Piezoelectrically Actuated MRI Robot for Transperineal Prostate Diagnosis and Treatment

    MRI prostate robot Parallel small.JPG

    Prostate cancer is the most common male cancer and the second most common type of cancer. MRI is an ideal guidance modality with the ability to perform high quality, volumetric, real-time, multi-parametric imaging with high soft tissue contrast without ionizing radiation. The objective of this project is to develop highly sensitive and accurate image-guided interventional robotic system, which can be readily integrated to clinical work-flow, for targeted core biopsy as well as focal delivery of therapeutics to locally advanced tumor sites within the prostate.

    I have developed three versions of MRI-compatible piezoelectric actuated robot for prostate biopsy with real-time in situ needle steering capability in 3T MRI. The 6-DOF robot consists of a modular 3-DOF needle driver with fiducial tracking frame and a 3-DOF actuated Cartesian stage. The needle driver provides needle cannula rotation and translation (2-DOF) and stylet translation (1-DOF).

    Development and Evaluation of MRI-Compatible Sensors

    FPI small.jpg

    Traditional sensors in robotics include force and positioning sensing. However, off-the-shelf sensors are not suitable for use in MRI due to the potential for image degradation, malfunction, or safety issues. We are evaluating and developing sensors to be used in the MR environment. The current focus is on optical techniques for force and position sensing that do not compromise image quality and will allow for haptic feedback during MRI-guided interventions.

    To re-gain the tactile feedback during needle insertion, we have developed two versions of fiber optic force sensors. The light intensity modulated force sensor can measure insertion force and bending moments. while the light phase modulated force sensor is a miniaturized sensor capable of detecting micro Newton level force variation. These devices will bridge the tactile gap often felt with a teleoperated system. The final goal is to design a teleoperated needle placement system that can plan the needle path and accurately align the needle with MRI guidance, while the fiber optic force sensor measures the insertion force and renders the tactile feedback.

    Integrated Hardware and Software for Surgical Robots

    IGTLink.jpg

    With increasing research on system integration for image-guided therapy (IGT), there has been a strong demand for standardized communication among devices and software to share data such as target positions, images and device status. We have worked on integration and development of components for OpenIGTLink, a standardized mechanism to connect software/hardware through the network for image-guided therapy (IGT) applications.

    Despite a substantial armamentarium of apparatuses and systems has been developed to assist surgical diagnosis and therapy for MRI-guided procedures over last decade, the unified method to develop high fidelity robotic systems in terms of accuracy, dynamic performance, size, robustness and modularity, to work inside close-bore MRI scanner still remains a challenge. In this work, we develop and evaluate an integrated modular hardware and software system to support the surgical workflow of intra-operative MRI. Specifically, the distinct apparatuses and methods include: 1) a robot controller system for precision closed loop control of piezoelectric motors, 2) a robot control interface software that connects the 3D Slicer navigation software and the robot controller to exchange robot commands and coordinates using the OpenIGTLink open network communication protocol, and 3) MRI scan plane alignment to the planned path and imaging of the needle as it is inserted into the target location.

    Humanoid Robot for Autism Interventions in Children

    Pabi small.jpg

    This project was initially conceptualized to design an novel neck mechanism for a humanoid robot, and later we decided to build a penguin humanoid robot to interact with Autistic children to aid diagnosis and even standardize the diagnosis procedure. Autism Spectrum Disorder impacts an ever increasing number of children. The disorder is marked by social functioning that is characterized by impairment in the use of nonverbal behaviors, failure to develop appropriate peer relationships and lack of social and emotional exchanges. Providing early intervention through the modality of play therapy has been effective in improving behavioral and social outcomes for children with autism. Interacting with humanoid robots that provide simple emotional response and interaction has been shown to improve the communication skills of autistic children. In particular, early intervention and continuous care provide signi?cantly better outcomes. Currently, there are no robots capable of meeting these requirements that are both low-cost and available to families of autistic children for inhome use. We are piloting the use of robotics as an improved diagnostic and early intervention tool for autistic children that is affordable, non-threatening, durable, and capable of interacting with an autistic child.
