Our founder

Dr Cansun Güralp

Founded in 2019. GaiaCode marks Dr Güralp’s return to academic and industrial seismometer manufacturing, 40 years after he first revolutionised the industry with the World's first ever broadband miniature feedback instrument.

In 1978 he patented a mechanism that used a triangular leaf spring anchored to a rotational point. In combination with a sensor mass of less than 120 grams and a differential capacitive displacement transducer, this ushered in a new era of seismic instrumentation.

Dr Güralp is once again bringing a novel range of seismometers to the market, making best use of cutting edge materials, electronics and electromechanical design to make further advances on behalf of seismology, science and society.

Design and Writing of Firmware

Paul Minchinton

Paul has been working with Cansun since 1985 when Cansun first started to manufacture seismic instrumentation for scientific research and industry. Paul graduated from The University of Reading with a 1st class degree in Cybernetics (with subsidiary Mathematics).

Paul stayed on in a part time basis for the next 35 years lecturing in Logic, Digital signal processing, Microprocessors and Heuristics. One of his main research areas was undertaken in N-Tuple neural networks. In parallel with the University he has been involved in various projects through his own company. The projects were very varied and were particularly involved in the design of hardware and embedded firmware for logging tools used in the oil exploration industry, these tools were particularly used at very high temperatures reaching 180 degrees Centigrade.

Paul and Cansun worked jointly on seismographic instrumentation for the oil exploration industry. Co-designing a variety of electronic/mechanical toys. Design of hardware and firmware for a seismic digitiser jointly with Cansun. His current work at GaiaCode is the design and writing of firmware for the TAU range of digitisers.

Paul is also the designer of CM24, DM24 FIR and IR filters.


Digital Test Engineer

Robert Aikman

Robert is a digital test engineer working on the TAU digitiser. He has 12 years of experience in evaluating, testing, and using seismic instrumentation and this work was jointly conducted with Cansun. Robert is currently working as project leader specialising in digital electronics.

Robert is particularly interested in the networking of seismic instrumentation and their installation for Earthquake early warning systems. Robert is also in charge of calibrating the high resolution digitiser TAU.


Head of Digital Products

Murray McGowan

Murray has been an integral part of our industry for more than two decades. Since completing his MSc in Computing science in 1996 at Imperial, Murray developed and coded a well-respected seismic acquisition and control software whilst being responsible for a seismic network in Scotland for more than a two decades.

Murray is most interested in creating innovative solutions to seismic problems through the use of advanced software.


Head of Alpha production

Maksim Alimov

Maksim is the Head of Alpha production with over 3 years of experience in manufacturing Broadband sensors – both electronics and mechanics. After Graduating from the University of Hertfordshire with a BEng with Hons in Mechatronics with Electronics Engineering, Maksim joined Gaiacode.

Maksim is also experienced in the installation of seismic instruments. Maksim is particularly interested in using his degree to help build precision seismic instruments.


Head of Mechanical design and manufacturing

Robert Kirrage

Robert is the head of mechanical design and manufacturing of Gaiacode mechanical products. With over 3 years of experience in seismic instrumentation design and bringing a wealth of over 10 years of experience in mechanical design, Robert has helped improve the design of all Gaiacode mechanical products through the use of CAD and manufacturing.

Robert has a passion in designing instrumentation which will revolutionise the industry.
