WORK EXPERIENCE

Engineering Intern July 2010 – Present

Intermountain Healthcare

• Developed software that acquires ECG and ABP data from a patient monitor using a National Instruments data acquisition system while parallely filtering the signal and finding the QRS peaks in the ECG data using an adaptive threshold algorithm and writing the data into a SQLite database.

• Developed an advanced interactive R-R wave artifact management software, which allows to user to,

o Remove incorrectly identified RR intervals and insert points manually after review.

o Interpolate for ectopic beats in the ECG signal.

o Exclude artifact affected regions.

• Developed additional software modules to do HRV analysis on the heart rate data.

Test Setup design for testing cerebral blood vessels October 2008 – June 2010

University of Utah

Designed a National Instruments based test setup which is used to perform controlled mechanical tests on human cerebral blood vessels and collect data about their mechanical properties. The following features were implemented.

• The test setup collects data from pressure transducers and load cells using a data acquisition system which is synchronized with a timer/counter module that reads data from 3 digital encoders, which then issues trigger to control a camera at certain data points to capture images synchronized with the data acquisition.

• Designed a feed-forward pressure control system and a temperature control system for the test setup.

• Used DLT (Direct Linear Transformation) calibration method to collect the real world 3D-Coordinates of the arteries under test (in order to measure the strain) from the images obtained from two cameras at oblique angles. (Matlab)

• Implemented Digital Image Correlation (DIC) method for markerless tracking of the samples by using polarized light to enhance the features. (Matlab)
