He is a past President of the Hong Kong Society of Theoretical and Applied Mechanics (20042006) after serving as member-at-large and Vice President. He also served as a Scientific Advisor of the Hong Kong Observatory of HKSAR Government, an RGC Engineering Panel member of the HKSAR Government for 7 consecutive years, and served as the Vice President of the Hong Kong Institute of Science. He held visiting positions at Harvard University (USA), Kyoto University (Japan), Polytech-Lille (France), Shandong University (China), Taiyuan University of Technology (China), the Rock Mechanics Research Center of CSIRO (Australia), and the University of Calgary (Canada).

Areas of Research / Professional Expertise

    Dr. Chau’s research interests have included geomechanics and geohazards, including bifurcation and stability theories in geomaterials, rock mechanics, fracture and damage mechanics in brittle rocks, three-dimensional elasticity, earthquake engineering and mechanics, landslides and debris flows, tsunami and storm surges, and rockfalls and dynamic impacts, seismic pounding, vulnerability of tall buildings with transfer systems, and shaking table tests. He is the author of more than 100 journal papers and 200 conference publications. His first book entitled Analytic Methods in Geomechanics was published by CRC Press in 2013.

Personal Interests

    In his leisure time, he enjoys swimming and takes part in master swimming competitions. He is the Honorable Manager of the Hong Kong Polytechnic University Swimming Team. Since 2001, he has competed in Hong Kong Masters Games, the Hong Kong Territory-wise Age-Group Swimming Competition, the Hong Kong Amateur Swimming Association (HKASA) Masters Swimming Championships, and District Swimming Meets of the Leisure and Cultural Services Department (LCSD). He has also participated in international masters swimming competitions, including the Macau Masters Swimming Championship, the Singapore National Masters Swimming, Standard Chartered Asia Pacific Masters Swim Meet, Wisdom-Act International Swimming Championship (Taiwan), Standard Chartered Singapore Masters Swim 2007, Japan Masters Long Distance Swim Meet 2008 (Aichi Meet and Machida Meet), Japan Short Course Masters Swimming Championship 2009 (Kyoto), Marblehead Sprint Classics (USA), The Masters Games Hamilton (New Zealand), Hawaii Senior Olympics, National China Masters Swimming Championships, the Third Annual Hawaii International Masters Swim Meet, and the Fifth Penang Invitational Masters Swimming Championship (Malaysia). By 2007, he had competed in all long-course FINA events (i.e., 50 m, 100 m, 200 m, 400 m, 800 m and 1500 m freestyle; 50 m, 100 m and 200 m butterfly; 50 m, 100 m and 200 m breaststroke; 50 m, 100 m and 200 m backstroke; and 200 m and 400 m individual medley).
    He also enjoys jogging and has completed four full marathons, including the Hong Kong International Marathon, the Chicago Oldstyle Marathon, and the China Coast Marathon with a personal best time of 3 hours, 34 minutes, and 15 seconds.

Book review by James Rice of Harvard University

By: Chau K.T.

Comments by James R. Rice on book “Theory of Differential Equations in Engineering and Mechanics” by Professor K. T. Chau.


I am delighted to recommend this highly readable book by K. T. Chau on differential equations as they arise in engineering mechanics and allied areas of physical science. It is essentially encyclopedic (running nearly 1000 pages) but consistently and successfully pedagogic. 


Professor Chau’s book is in no sense a simple litany of recipes for how to solve this or that class of problems.  Rather, the logic of the approach is carefully outlined in each case, starting at a simple intuitive level that beginning students, with no background beyond basic calculus, will surely find accessible.


Chau first builds on that background with a comprehensive Chapter 1 on “Mathematical Preliminaries”, introducing such as series expansions, complex function concepts including, e.g., the Cauchy Integral Formula and residue theorem, vector calculus (div, grad, curl), the divergence and circulation integral theorems, Taylor and Laurent series expansions, and even tensor concepts, illustrated in Cartesian, cylindrical and spherical coordinates.  And all that, like the following chapters, is interlaced with interesting historical tidbits and anecdotes, keeping the readers interest while attaining a remarkable level of presentation.  He is very successful, through a thoughtful presentation, well calibrated to beginners, in making all of that accessible and engaging. There are also lots of example problems, often with thoughtful informative comments, at the Chapter end.


Chapter 2 introduces simple ordinary and partial differential equations, as illustrations of classical particle and rigid body mechanics, electromagnetic theory (Maxwell equations), fluid dynamics, elasticity including plate and shell theory, and elastodynamics.


Chapter 3 then continues with a rigorous, essentially encyclopedic, general treatment of ordinary differential equations, again with Chau’s characteristic clarity of presentation.  That focus continues into Chapter 4, addressing series solutions of classical types of differential equations and properties of the multiple “special functions” defined by their solutions.  This is classical material, presented in various other textbooks, but I think Chau makes it all unusually approachable for students. Chp.5 continues that into systems of ordinary differential equations.


The focus then turns to solution methods for partial differential equations, beginning with first order in Chp. 6 and higher order subsequently in Chp. 7, with special reference to the classical elliptic, hyperbolic and parabolic pde’s arising in such as fluid dynamics, thermal science, elasticity and structural mechanics.  Next comes a Chp. 8 on Green’s functions for linear pde’s and the reformulation of pde problems as integral equation problems.


There follows a Chp. 9 on the classical Wave, Diffusion and Potential pde’s, including their applications in mechanics, thermal science and electro-magnetism, and then a Chp. 10 on Eigenfunction expansions and their applications to solving pde’s.  Next comes a Chp. 11 on integral and integro-differential equations, including the classical integral transforms (Laplace, Fourier, Hankel, Mellin, Hilbert and another 10 or so lesser known transforms), and examples of solved classes of integral equations.  As is characteristic of  Professor Chau’s presentation, there are lots of solved examples, and procedures are nicely illustrated with effective graphics.


Chp. 12 addresses Asymptotoc Expansions and Perturbations, Chp. 13 the Calculus of Variations, and Chp. 14 Variational and Related Methods. And an expansive closing Chp. 15 addresses Finite Difference and Numerical Methods.


There are hordes of useful Appendices, mostly on mathematical details, but also one including capsule biographies of roughly 75 major figures, running alphabetically from Abel to Wronski.


Again, the presentation is distinguished for its accessibility and carefully thought-through graphics -- Professor Chau clearly understands how to write appropriately with a student in mind (and in a manner much appreciated by this reviewer).
