    We have taken our innovation on shock wave assisted fracturing in rocks (two patents) through faculty entrepreneurship programme at IISc and started a company where in IISc owns 10% share. We have completed the lab trials and numerical modeling of the shockwave assisted fracturing in rocks/shale. We have also received Rs 58 crore projects for field trials and implementation with ONGC, Govt of India. Signing of this MOU with SWTPL and ONGC was done in presence of Honorable PM Sri. Narendra Modiji, Govt of India at IISc, Bangalore on Feb 18, 2015.Scope with ONGC involves: Design, fabrication and installation of calibration rigs and shock wave fracking tools, field trials of different shock wave fracking tools in ONGC wells and evaluation of performance of the wells for assessing effectiveness of treatment and documentation of laboratory and field trial results and joint IP protection.

    (Started under IISc faculty entrepreneurship programme). IISc -10% shareholder of the company. IISc in principle agreed to provide office space, startup fund and patent licensing.

  • Director, Sarathy Geotechnical and Engineering Services (Since 2009), Bangalore

    (helped Dr. Partha to set up his own startup after graduating from IISc and it is a well-established company now). Today it has employed 75 people and grown big with a turnover of about 10 crores. Has presence in India, Indonesia and Africa.

  • Director of Sky Group Advisory Board, Sky group- GIS consultant and Services (since 2007), Bangalore
  • Rashtriya Avishkar Abhiyan, MHRD- Role in National Innovation System (NIS)

    A team of 4 senior professors from IISc along with Prof. Sitharam suggested the concept of Rashtriya Aavishkar Abhiyan to Honorable Minister of Human resources Development based on both bottoms up approach and top down approach. This is in pursuance of the focus on connecting school based knowledge to life outside the school and making learning of Science and Mathematics a joyful and meaningful activity, to bring focus on innovation and use of technology and also Innovation training and nurturing spirit of enquiry and creativity among engineering and science institutes of higher education like IITs, IISER’S and IISc to encourage and support academic excellence. Ministry of Human Resource Development has already set up the Rashtriya Avishkar Abhiyan(RAA) - a convergent framework that aims at nurturing a spirit of inquiry and creativity among all stakeholders and the same was launched by MHRD on 9th July 2015.

  • Initiated several activities in this area of Innovations through AICTE as Chairman, South western Regional committee of AICTE such as National Projects exhibition at Alpha College of Engineering on May 14, 2016; Apprenticeship training (NEEM) on 20th April 2016 and Focus Career pathway 2016 with Vijnana Bharati.

Instruments Developed

1. Development of piezo vibro cone system

State-of-the-art hydraulic servo controlled piezo vibro-cone equipment, has been developed jointly with M/s HEICO, New Delhi as part of DST funded Research Project. The proposed piezo vibro-cone consists of a cone penetrometer coupled with a hydraulic shaker to induce liquefaction locally in the vicinity of probe during penetration at desired depth. The piezo vibro-cone has been designed to have three built-in sensors: (1) Load cell for tip resistance, (2) load cell for skin resistance, (3) Piezo sensor for pore pressure measurement. This facility has been installed at Soil Mechanics Lab, IISc, Bangalore.


2. Development of cyclic triaxial testing facility


The state-of-the-art cyclic triaxial testing facility installed in geotechnical engineering division was developed with the financial support from Department of Science and Technology (Seismology division), Govt. of India, New Delhi, which is used to study the behavior of soils subjected to dynamic loading, liquefaction behaviour and also to estimate the dynamic soil properties such as shear modulus (G) and damping (D) required for design of geotechnical structures subjected to earthquake loading. The system is completely automated and computerized, which consists of servo-controlled submersible load cell (with a capacity of 10 KN) and a hydraulic actuator with frequency range of 0.01Hz to 10 Hz for applying vertical dynamic loading on the sample. The validation of the system as well as majority of development of computer control software for the system was done by me.

3. Development and installation of Uni-axial shake table facility

Shake table facility, which has been indigenously fabricated by M/s BISS, Bangalore, has the following features. Usable Table size of 1m x 1m, with a provision (i) to fix hydraulic actuators, velocity and acceleration transducers at the appropriate locations; and (ii) to have alternative top plates to represent different roughness of the table-model structure interface, iii)30 kN servo-actuator for horizontal motion. Hydraulic actuators along with a computer and software for the generation of the input signal; cyclic function generator with a frequency range of 0.001 to 100 Hz. My contribution particularly focuses on foundation system for the shake table, civil structures for the facility and development of lesser weight earth pressure cell, accelerometers and pore pressure sensors.

4. Development of state of the art Laminar Box


A complete design and scaled drawing was provided to M/s Biomed Instruments, Bangalore for fabricating laminar box. A laminar box is a large sized shear box consisting of several horizontal layers, built such that the friction between the layers is minimum. Hence the layers move relative to one another in accordance with the deformation of the soil inside. The present laminar box which incorporates the idea of rotation of end plates is designed and the same was manufactured by M/s/ Biomed Instruments, Bangalore.

5. Advised Wadia Institute of Himalayan Geology for setting up a state-of-the-art Geotechnical testing laboratory at WIHG

Responsible for establishing two new areas of research In the area of “Rock mechanics and Rock engineering “ and In the area of “Geotechnical Earthquake Engineering”, at Department of Civil Engineering, IISc, Bangalore and developed new courses in these areas of post graduate teaching and organized several national conferences including one brain storming session on earthquake geotechnical engineering. Also he is the author of two books for undergraduate education (Applied elasticity and Geotechnical Engineering Vol I and II) and authored many web courses and edited several conference volumes.
